It clearly states Dolby Surround and Dolby Pro Logic Systems. This is from the VHS days. DVDs support Dolby Digital 5.1 and DTS. This is plain nuts. Not only are you getting slightly inferior picture, the sound is ancient. Dolby Surround is nowhere as good as Dolby Digital. Here is a simple explanation.
Dolby Surround uses two tracks of audio to encode 4 tracks. The two additional tracks are for the center channel and a single rear channel. The single rear channel is not full spectrum (20Hz - 20kHz), but rather something very narrow.
For comparison, if you have a good surround sound system (I am not talking about the $200 Home Theatre in a box system, but a system that cost at least $1000), play a DVD that has both Dolby Surround and Dolby Digital. Play with the Dolby Surround track first and then play with the Dolby Digital track next. Huge difference. I am disappointed. Surely, there is a way they could embed discrete surround with AAC.
The specs for Dolby Digital is as follows: 5 tracks of discrete digital sound full spectrum 20Hz-20kHz. One channel for LFE (low frequency extension) - topping out at about 120Hz. That is why you have 5.1.
Dolby Digital is lossy compression though but still you have 5.1 channels. DTS is another lossy compression format but has a higher bit rate and sounds better than Dolby Digital. DTS typically have about 760kbps while Dolby Digital is about 448kbps.
HD-DVD and Bluray Disk support Dolby TrueHD that supports 8 channels of lossless sound upto 18Mbps. Cool. Well, we are way off from there.
I don't think Apple is aiming for the uber-geek with $25k worth of home entertainment equipment. IMHO, they will never be able to compete in that market.
I think they are reaching for the average joe blow that has a servicable $400 TV that he bought at Wal-mart, and maybe, just maybe, has a stereo hooked up to it. The average Joe doesn't care, and can't tell, that it's Dolby Surround and not Dolby Digital.

The only way that would happen would be for the phone to be GIVEN away at a price so LOW that nobody would refuse it. And it would have to include a data plan that costs practically nothing. And it would have to be contract free.
Oh, look! There is an ad below this for HTC Aria� for just 1� - Free shipping - AT&T.
That's kind of where I was going... but businesses would switch from Blackberrys to Windows Phones. I wouldn't put it past MS to offer some sort of crazy business discount to get companies to change.

I wouldn't be surprised if the iMac and new Mac mini are the replacement for the Mac Pro...
By the time November comes around, Thunderbolt may cause the death of the Mac Pro.
Your logic is half-baked. The MacPro has one specific function which the iMac will probably never have: instant customization. You can stack tons of drive space in them, tons of RAM, and choose any sort of monitor config.
Sure, iMacs might be able to do something like that, but with a lot of garbage floating around and cluttering everything. Also, the processors in the Pro are always beefier.
However, I'd agree that for almost all people in the market, an iMac would be just as good as a MacPro. In 4 years I will probably replace my 2007 Pro with an iMac. Spending $4000 for a good Pro isn't worth it compared to $2000 for an iMac.

Looks to me like a combined MS/Nokia actually LOSES marketshare. (26.4% down to 21.1%) - funny how the 'report' doesn't spin the numbers that way. I do find it humorous that these analysts think they can see 2015 with any semblance of accuracy.

Contrastingly, if you need to not have one, you can always buy a MacBook Air. I don't use my FireWire 800 port often, but when I do, I'm thankful it's there. The same goes for the optical drive. Again, if you don't want it, Apple makes the MacBook Air which comes without it for the truly space-concious.
No I can't just get an Air. Not if I want a quad-core i7 dedicated graphics, an SSD boot drive and a 1TB HD for data. That sounds awfully "Pro" to me.

LOL at everyone freaking out!! So Google can take pictures of your house, back garden, car etc and post them for the entire world to see without asking you first, Facebook would sell your soul for profit if it could, and your worried about Apple tracking your phone, most likely for it's Find My Phone feature? hahahaha.

because the p910 when released was a $AU1300 phone. i dont want to be paying for that TWICE (no phone is free. u either pay up front or you pay in your monthly contract) if i change carrier. you dont get a new Mac because you change ISP, do you?

You might be right, I am not going to discuss specifics. but the truth of the matter is that the quality of a DVD is better than the 640x480. Even Apple stats that on their site.

That's what I was trying to convey.

Yea, I understand. I too would neverthless have liked 720x480p....

Apple seems (http://www.macrumors.com/2011/04/21/apples-cloud-based-music-service-ready-to-go/) to be getting ready to launch their cloud-based digital music "locker" service that has been rumored for many months. But contrary to an earlier Reuters report, All Things D (http://mediamemo.allthingsd.com/20110421/one-difference-between-apples-music-locker-and-amazons-label-deals/) has heard that Apple has already come to terms with two of the four major record labels about the service, and that Apple's Eddy Cue will be in New York tomorrow to try to finalize the remaining deals.
The negotiating of these deals is in contrast to Amazon's music storage service (http://www.macrumors.com/2011/03/29/amazon-launches-cloud-based-storage-service-and-music-player/) which notably launched last month without any deals in place -- a fact that the record labels were not very happy about (http://www.reuters.com/article/2011/03/29/us-amazon-idUSTRE72S13H20110329). Apple is said to have been "very aggressive and thoughtful about it" and "It feels like they want to go pretty soon", according to an unnamed music executive. All Things D also provides some details about how the service might work from Apple:The industry executives I've talked to haven't seen Apple’s service themselves, but say they're aware of the broad strokes. The idea is that Apple will let users store songs they’ve purchased from its iTunes store, as well as others songs stored on their hard drives, and listen to them on multiple devices.All Things D points out that having official licenses can allow Apple to store a single master copy of a song rather than storing individual copies for every user. Amazon's original argument against needing the licenses was that their service was the same as any upload storage service. This meant that users needed to upload copies of their old music to be able to stream them. With the proper deals, Apple could avoid the need to upload individual copies and simply allow users to stream off of the single master copy. This could save on significant upload time for the user and storage requirements for Apple.

Ok but didn't someone say that CMD + Drag does the same for files?
Yes. Which was also mentioned that cmd+drag is very inconvenient and a hassle to deal with the majority of the time (or at least in my opinion.)
Why Apple just doesn't just enable cmd-x in Finder is beyond me. It would make my life just a little easier at times.

Please explain - I have no idea what "that" is....
---
Regardless of the tool, however, it is usually much better to let the OS dynamically schedule threads across the cores. Unless the programmer has some reason to try to control this, the alternative is some resources (CPUs) being overcommitted, while other CPUs are idle.
It doesn't matter who has the better tools - it's usually better to let the OS decide microsecond by microsecond how best to schedule the CPUs, than to have the developer make those decisions at edit time.
I've used the SetProcessAffinityMask APIs fairly often, but it's always been for specific test or benchmark situations. I have a hard time thinking of a situation where a general application would want to statically control the scheduler - it's just "bad think" to even try. (Except for those weird-a$$ NUMA Opterons - you can be really scr3wed if you have to go through HyperTransport to get to memory. I check NUMA topology, and use affinity to keep the AMD architecture from killing me.)
I've owned SMP machines in the past and often found it more useful to force CPU affinity of CPU-heavy tasks to a single processor, as Windows 2000 (which was current at the time) by default had a habit of swapping it between chips, resulting in a lot of cache-dirtying. I think it was the load balancing code, but it's been a while now and I don't have those machines handy currently. However, you could see some significant improvement in processing time on some non-parallelizable cpu-bound tasks.
I've no idea if MacOS does this, but at least in the case of Core 2 it shouldn't matter anywhere near as much, as the L2 is fully shared.

There's no chance apple is releasing MBP's tomorrow. There are too many things pointing towards early/mid-Sept.
There's no question that apple will not *ship* merom machines tomorrow. But there's nothing stopping them from making the announcement and taking preorders.
