I'm kind of caught between a rock and a hard place.
Speed is important for me: CD-burning, video-editing, animation-rendering. For that reason the last computer I bought was a Quicksilver. It was the obvious choice at the time.
I imagined that my next computer would be another Mac to replace my ageing PC. Now it's not so clear. From the informed posts by new P4/XP users on this site it's clear that PC could do the things I want it to do more quickly and, arguably, with comparable stability.
BUT, I'm an expat living in Japan. One huge advantage of OSX is unicode. My Mac has a Japanese OS, which is great for my wife, but when I'm using the Mac I can switch the user language to English. Much of our Japanese software is also unicode compatible, so we can buy one program that can be used in either of our native languages. This is very cost-effective in the long-run.
I'm prepared to wait until next year when, hopefully, Apple will be using G5 chips from IBM that are much closer to those from Intel/AMD. I don't need my Mac to be the fastest computer out there (the advantages of OSX would bridge the gap) but I want it to be comparable if I'm going to shell out the extra bucks.
I don't really want to use XP. On-line activation and security issues still put me off.
If, however, Apple fail to deliver an impressive new hardware set next year, my next computer may well be PC.
I hope not, but you have to be realistic...

Since I'm not a video editor, what I find most interesting about this product is the price. Mind you, time will tell HOW interesting the price is but if it's truly a "Pro" app (and I don't care about your current opinion on the matter since no one here has used it) and they're selling it for $300... THAT is very interesting.
I'm curious to see what Lion sells for when it's released. I think Apple's gonna start pushing software prices down. How's that for weird?

I think this will be a great first step for Apple. Long term, I'd like to be able archive all my DVDs and play them through iTunes, just as I have done with my CDs. In the mid to long term, this would mean that Apple would have to work out a deal with a DRM solution with the content owners that would allow for a DVD (obviously this would not work with my currently owned DVDs) to be stored on a computer - authenticating back to the content owner's server, for example.
It may not be worth it, as everything will likely go to digital delivery anyway, in time.
I also would like a DVR, but in the long run, the traditional delivery model of TV will likely change. iTunes is a small foretaste. This would be huge, as it would necessarily change where, who, and how advertising dollars would be made. I betcha this will be keeping the cable, network, and movie execs up at night thinking through how they can control this potential shift in power and revenue to their own benefit.
All I know is I want to get rid of all the boxes surrounding my TV and speaker system, and be able to control all my TV, video, and audio assets through the TV - in the kind of eloquent way that it seems only Apple is capable of (I am sure this is not true - but I believe they have the best shot at providing an end-to-end user-friendly system).
The next few years are going to be very interesting.

Furthermore, if you are using iTunes music, and you are using iMovie/iDVD, you CAN use tracks in your videos. They import in and you can use them freely in your projects.
Except there have been threads where people did this and when they sent it to friends to view, their computer had to be authorised to do so.

No surprise the iPad is just a fad and people are starting to realize how limited it is. Its frustrating on a lot of cool websites and no file system makes it very limited.
Stuck record! Same old comment, still not true.
They can sell as many as they can make, production is the limiting factor at the moment NOT lack of demand.

My response to that TXT msg would be...
Did you know... I don't give a F|_|C|< !!!
and if you change my plan I will cancel my subscription and not pay a disconnect fee.... they may charge it... but I will never pay it.
I feel it is wrong to double charge someone for there data usage... It should not matter how you use your data... you paying for a certain amount and if you don't go over that then why should it matter. And to all of you that say there stealing something by tethering... there not... they paid for the data already... who are they hurting by using it on another device... no one... if at&t says they can't handle the network load then they need to upgrade there network.. or stop selling data capable phones. Oh and the thing about the unlimited plans... if its not unlimited... then don't say it is... that's false advertising... and I don't care about the fine print either.... they should not be allowed to advertise unlimited with out it being... umm.. well unlimited... and I know they don't offer it anymore... so if they want to get rid of it... when there current contract expires... take it away... done deal...
Before I get flamed to death here are some facts....
1. yes my iphone is jail-broke
2. no I don't tether... hell I only have the $15 plan and never go over it.

I'm not pleased with this development, because Apple's DRM is necessary to maintain the compromise they made with the record labels and allow the iTunes Music Store to exist in the first place. If the labels gets the jitters about how well Apple is controlling distribution, that threatens a good part of our "supply" of music, even though I wouldn't expect a large percentage of mainstream customers to actually use a program like PyMusique.
Will Apple be able to teach the iTunes Music Store to distinguish the real iTunes client from PyMusique with software changes only on the server side? If not, I imagine that only an iTunes update (which people would have to install) could stop the program from working.
Suppose iTunes is updated to use a new "secret handshake" with the iTunes Music Store in order to stop other clients from spoofing iTunes. Will iTunes have any way to distinguish tunes previously purchased through PyMusique from tunes acquired from other sources, i.e., ripped from CDs? Perhaps the tags identify them as coming from iTMS and iTunes could apply DRM after the fact. Then again, tags can be removed.

Every time it happens (I seem to get a string of dropped calls about once a month) I call ATT customer support. They talk as if this is unheard of and "we'll get this fixed right away". So far they have replaced my SIM card for free; they said the next step is a new phone.
I was hoping for a reduction in monthly price. We'll see.

...The think that worries me is that there is no mention of this device being able to play non-iTunes movies. What about if you back up a DVD to your computer. Can you play it on this? We'll have to wait and see.
I am willing to bet if you backup all your DVD's and then run them through handbrake you'll be set. Take all those 500-1.5GB mp4 files and drag and drop 'em into your iTunes. Then the 'iTV' would see them and there's your movie collection easily accessible.

I'm sure that if I cared about Greenpeace, I might care about this news. But honestly, I really could not care less about them. So I don't care.
People like you (who don't give a rat's a$$ about environmental issues) are exactly what the world needs more of at this point in time.
Not caring about the morons at GP, PETA, etc has nothing to do with the underlying issues. I care about eating a good hamburger, but McD's "can suck my left toe."

I haven't read this entire thread, so this might have been said already...I just wanted to point out that "hard drive" is an extremely generic term when it comes to layman's terms regarding computers. The corporate environment is full of less than technical users who don't know the difference between USB and Firewire, let alone what exactly a hard drive is. I have users that refer to the entire COMPUTER as the "hard drive". There is a very good chance that Iger knows very little about computers and could simply be miscommunicating what he means.

That's fine for soaking up occasional peak demand (I linked to 'vehicle to grid' techology a few posts back), but not providing energy for a full night... unless you have a link that says otherwise?
The obvious real answer is a globally connected power grid with generation all over the place so as night is not such an issue. Of course we'd need to agree on voltages, frequencies, cost etc.

Long post, my apologies.
No apologies needed. It was well-said, and I agree with you completely.
The ongoing justification of bypassing or defeating the DRM, as though this is somehow a "moral" action is pathetic. Period.

I have consistently had problems with dropped calls ever since I switched from the original iPhone to the iPhone 3GS, they replaced my phone twice because of it. It would work for a while, but then drop calls, or get 10 call failures before actually placing a call, just to be dropped minutes later...
Yesterday I finally upgraded to 4.0.2 and it is even worse! Not only do I barely get any signal in my house, even when it shows I have a signal it still doesn't work. The problem seems to be when it goes into sleep mode it disconnects, because when I unlock it, a swarm of text messages and voice mails from missed calls I never received pour in...
I finally called up AT&T to see if there was anything they could do (maybe give me one of the femtocells to keep my 5 iPhone family plan happy (bill is almost $300 a month)... I was greeted by an unfriendly and unhelpful customer service agent. She pretty much told me there was nothing she could do (and when I asked about the femtocell she had no idea what it was, didn't even offer for me to buy it), and then she said its just the network, it happens to her all the time, I am probably in an area with poor coverage.
I told her to look it up on the AT&T coverage map it shows "best coverage" all around my house and where I live, pretty much most of Long Island. To which she said "coverage is not at all guaranteed", I flipped a bird and said "what the fu*k does that even mean, so I can get an at&t phone and pay for the service and you can't even guarantee I get service in any location around the world, even if you advertise it" to which she responded "yup". And I said, that's just ridiculous, I might as well switch to a carrier such as sprint or verizion (my parents have one of each) and they get service in our household. And then she said "Go ahead and switch". I don't remember exactly what I said after that, but she followed with other dumb remarks, such as, it could just be what your house is made of, or do you live underground? I'm sure I live in a cave lady... But I really can't bash all the Customer service agents at AT&T, some are great and very helpful.
Never the less, I was very pissed and disappointed with how AT&T is handling itself. Never have I had such poor customer service. When I had nextel and complained about their crappy service, they were very apologetic and offered me free stuff, and even if I never mentioned dropping them, but even hinted at the possibility, they would offer me upgrades and the works just to keep me... AT&T is just hit or miss, when the network works, its great and super fast, but if your in a high traffic or any other area, its the pits... Which is why I think people on the forums have such a hard time understanding these complaints. I bet the reason for the big change in satisfaction surveys has to do with geographic location. When I was in any other state but NY the service worked when it said I had service, but even then I could have full service, travel 10ft and get No service to show up on the iPhone, very spotty at best.
I am definitely going to switch my entire family plan over to verizion when our contracts are up in a year, I really hope they get the iPhone, if not, droid here I come! But to the rest of the community, has this ever happened to anyone else but me? Should I call back AT&T, at this point I would be willing to buy the femtocell, my phone doesn't work in passive mode, only gets service when I am on it and unlocked.
EDIT:
I actually looked up the femtocell, which is now called microcell to make sure I wasn't going crazy and to see if it is available in my area (which it is), and I saw a video that I just find hilarious! If you go to the following link and click on "increased signal strength" in the interactive video that loads on AT&T website for the microcell, it starts to play a video that actually shows how crappy their service is, with the guy having to hang out of the window to make a call... WTF? AT&T should fire whoever makes their commercials...

I have not *ONCE* had either one core dump or "blue screen". Sure programs screw up, and when they do, they die, not the OS. Both OS's are very mature.

Winamp uses 0-1% CPU, iTunes consumes 8-12%.
3.) You speak of flaws of the "x86 architecture" but do not provide us specifics as to why you say this. The x86 processor began in the late 70's when Intel first offered the 8086 as a CISC successor to it's 4004 line of processors. Many, many things have changed over the course of 20 years. Had they sit still (like the G4/motorola chip) intel wouldn't be selling products today, now would they? The G4 is not much more than an improved G3 series processor with vector processing instructions. Be honest (especially be honest to yourself!) if you look back and compare the G3/G4, you do see improvements, but not drastic improvements. More clock, the maxbus protocol (debatable), and more cache. One of the reasons why you see Apple adding cache like mad to it's recent products is because they are in between a rock and hard place with this Motorola chip. This is exactly the same approach AMD took with their failing processor, the K5/K6. I want you to contrast this to a P4 with an i850e chipset: Insanely high clock speeds, a 533mhz bus, fast memory with RIMMs @ 4.2GB/s, with a next stop of 9.6GB/s -- to MaxBus. You will soon see why the current generation of PowerPC processors is "inferior", dare I say it.

well i might be getting a mac pro soon (not sure yet)
but if i do, my question is when will we see an 8-core mac pro?Revised semantic perfection:Probably November or December at the latest. It will Probably simply be a Dual Clovertown Processor option added to the current BTO page with a new processor pricing lineup. It will Probably be a silent upgrade with a press release.How do you know this for a fact? :confused:I don't. But since they ship in November, I imagine Apple will roll them into the line in December since it's simply a matter of installing a different pair of processors into the same motherboard without even a firmware update. I could be wrong. Went back to the original post and revised it.

And gravity has yet to go up. :p LOL
While the idea is ridiculous Lewis Carroll (who was a mathematician amongst other things:rolleyes:) did some work on the problem and in a fictional work came up with this:
"In Chapter 7 of Lewis Carroll's 1893 book Sylvie and Bruno. The fictional German professor, Mein Herr, proposes a way to run trains by gravity alone. Dig a straight tunnel between any two points on Earth (it need not go through the Earth's center), and run a rail track through it. With frictionless tracks the energy gained by the train in the first half of the journey is equal to that required in the second half. And also, in the absence of air resistance and friction, the time of the journey is about 42 minutes (84 for a round trip) for any such tunnel, no matter what the tunnel's length."

"In Chapter 7 of Lewis Carroll's 1893 book Sylvie and Bruno. The fictional German professor, Mein Herr, proposes a way to run trains by gravity alone. Dig a straight tunnel between any two points on Earth (it need not go through the Earth's center), and run a rail track through it. With frictionless tracks the energy gained by the train in the first half of the journey is equal to that required in the second half. And also, in the absence of air resistance and friction, the time of the journey is about 42 minutes (84 for a round trip) for any such tunnel, no matter what the tunnel's length."

I remember getting my old Power Mac 7500 in an ugly brown box with a message on it saying that apple wasn't using dyed boxes in order to help the environment. That's fine with me. However, I retrospect, I promptly dumped that box in the trash and acutally still use my newer and prettier dyed Apple boxes as storage containers in my storage room--something I never would have done with the ugly, wimpier brown one. So much for the borwn box helping the environment.
IMHO, Greenpeace is not to be trusted. They are highly-biased activists who, like most activist groups (right or left), have the unstated, main goal of needing to justify their continuing existence. Greenpeace, in particular, is notorious for having blinders on to the point they don't have any perspective in the real world beyond the utopian fantasies. I'm all for having reasonable, workable policies that are responsible and benefit society, but letting Greenpeace be the dictator of what those policies should be is naieve and dangerous.

If I've harmed anyone in anyone in any way, I want to hear about that from the harmed ones. Everyone here is welcome to his opinion about me. If anyone here hates me, he's welcome to say so publicly or privately. But I think I'm the only one here who knows whether I hate anyone. We're strangers to one another.I do not hate you in the least, but I do recognise hateful, dogmatic propaganda when I see it.

Those priests obviously weren't celibate, then.
Yes, it really does suck that there are bad people everywhere.
I know, right? You can't blame the Catholic Church because some of their chosen leaders like to diddle children. Sickos are bound to be found even in the most pristine of institutions.
What really sucks is how the leaders of the Catholic Church covered up this abuse and allowed it to continue. Surely they will burn in hell over that.

Of course as with all nuclear disasters there's the usual 'don't worry, it's not that bad' while at the same time they evacuate 45,000 people from the immediate surrounds..
Analysts say a meltdown would not necessarily lead to a major disaster because light-water reactors would not explode even if they overheated.
Well, that map seems to show Japan itself will be okay from the fallout at least.
EDIT- They've extended the evacuation radius around the #2 plant to 10km, the same as the #1 plant. The #1 plant is the one which had the explosion.

Yes, I strongly disagree that students need to learn Windows in order to thrive in the workplace. Nowadays work is being done in browsers more than anywhere else, and that trend will continue inexorably as we move to the cloud future. Kids need to learn how to use a computer. Which one is not that important any more. Times have changed.
And on the topic of laughing at OS X market share, keep on laughing. Apple is the most profitable computer company on the planet. Dell and Microsoft wish they had Apple's problems.

If he did that, he goofed. But I know I made a mistake: I missed your point. Now I understand it. Thanks. Maybe he tried to communicate with me in Latin because he know I usually attend the Traditional Latin Mass.
Indeed sir, that is why I tried.
