The volume buttons are a little stiff, though the sleep/wake button is perfect. I'm hoping the volume buttons will loosen up a bit over time. I can adjust them pretty easily with my pointer finger when held in my right hand, but I can't do it very well with my thumb when holding in my left hand.
I completely agree with you on this, the sleep/wake button is fine using either left or right, BUT the volume rocker is not convenient when using left hand, but right hand is ok.

Nop... consider.
2x CPUs 130W rated. So thats 260W, right there. However, no CPU consumes the rated, so it's give or take ~260W.
Each 5770 is ~108W, given two, that's ~216 W. Right off the bat we have ~476 W being consumed. Not bad; however let's look at the side where its not a dual 5770 setup.
The PSU on the Mac Pro is rated for 980 W of power, but for simplicity sake let's say 1 kW. Now, factor in the Super drive, Ethernet, Airport, at least 1 HDD and peripheral docks/cards you are looking at ~100 W. Take into account a 20 W per 1GB of memory (assume 6GB) and you've got ~120 W more. So far ~ 220 W more.
Now we have ~480 W [~260W + ~220W]consumption leaving only ~520 W left for a GPU. Currently, the HD 6970 requires 2x 8-pin connectors to provide 150 W per pin. That's 300W right off. So we are left with ~220 W in the system. Now, factor in that PCIe slot power draw at 75 W and we've got a ~145 W left over. ~145 W is cutting it too close and something will yield (yes I do realize 145 W is a lot more, but read on). Now, the sad part, we were assuming 1kW PSU which is not the case; it's 980 W meaning there will be less power, ~125 W. Now, also take into consideration no PSU is 100% efficient, hence there will be greater power outlet draw and the PSU will be operating at high voltage/amps and its life span will decrease dramatically over very high usage.
In other words the current PSU may come up short. Add to that the fact that all current shipping and past model Mac Pros don't have extra dual 8-pin connectors. They have dual 6-pins. There is an adapter to make a 6-pin into an 8-pin, but it is risky at best, big no-no.
So as you can see an HD 6970 would be barely supported on current models. Future models? Perhaps yes assuming Apple bumps to 1.1kW or 1.2kW PSU.
Take into account this was calculated assuming 6GB of memory and 1 HDD, anymore RAM (20 W/1GB) or HDDs (10W/disc) and the consumption will go up. Also, assuming nothing is hooked up to peripheral ports; like a small external drive that draws 5-10 W.
I have an 850 watt PSU in my gaming rig with a 4870x2 and custom coolers all around on the CPU, GPU, and case. I think your calculations are pretty close to correct if you wanted to run everything in the case at once. But that's not typical to run everything at max all at once. I suppose Apple might not want to get in the business of telling people it's okay to buy this honking huge GPU as long as you're not running a lot of extra hard drives and extra PCI-E cards.
But, for people looking to simply drop in a fast GPU and not have a lot of extra bells and whistles (read: a gaming rig), they would be fine with 850 watts or so, even with a 6970. Or at least damn close.
The tricky part with GPU's is that the high end units commonly exceed rated specifications at max load, so these calculations are tricky. And your point about running too close to your max is also a good one. It's fair to say that when you add up all your max dissipation, add 20% or so, and that's the wattage your PSU needs.

I've been ready to buy, and waiting for a merom-based MBP since July, but I almost hope this turns out to be wrong.
A quite Tuesday speedbump would most probably mean a simple chip swap, and that these new MBPs would be otherwise just like their predecessors.
I'm rather hoping for a significant enclosure redesign (easily swappable hdds, magnetic latch, better ventilation, etc. and black anodized aluminum would be nice), as well as significant component changes (802.11n, better GPU, crestline chipset, etc.).
So I've rather been hoping for an 'event' at which these significantly upgraded MBPs could debut. I doubt the kinds of significant changes I'm hoping for would be released without some sort of fanfare.
Cheers

For the sake of those who want to remain surprised until we see the video, there should be a page on MacRumors that says "will post link when video available" - so I can just check that page for the video to be uploaded later in the day. I plan to completely avoid all news until I see the video.

But the rebels are not in contact with the rest of the world through any official channels, and media access is poor.Twitter (http://twitter.com/ShababLibya) is informative, but after 42 years of impotence, normal service cannot be resumed instantaneously. The prospects seem remarkably good, though, that what emerges from this will be an unusually honest democracy.

This is HUGE, ginormous news. If Lion, or even later released of Snow Leopard, has this kind of support, ti would revitalize the Mac gaming scene. Even 3D artists would have more options, especially when you consider how well the high end consumer cards stack up against their FireGL competition.
Now all they need is complete 6900 series support-- yeah, I'm lookin' at you, 6990. ;-)
Not likely since Steve Jobs isn't smart enough to do that. Heck, he still believes that glossy displays are a cool idea.
I almost gave up on the MacPro until Steve forced me into a 'NON-GLARE' NEC PA271, and all I can say is wow! Even with the pithy GT120 card-less piece of crap offering by Apple, the screen looks fantastic.

Actually, you can get Sirius in Canada and are able to stream Sirius anywhere in the world IF you have an account registered in the US. I've heard of many international customers setting up accounts to listen abroad.
I'm just saying that I think the two would compliment each other nicely. You could use the service as just an ipod, a receiver for Sirius or BOTH.

D) Change the remote- no offense, but this remote needs a few more buttons, considering it may drive a media hub.
Well, then you don't understand Apple's magic. That's precisely where
they are good at: make complicated things simple.
It's like a Sony TV remote control compared to others : when you use it, you find everything else too much complicated...

Why do some people think Steve Jobs doesn't want a movie rental model? Traditionally, music is sold, not rented. Traditionally, movies are rented, not sold. I see jobs pushing this for iTunes. I'm guessing Apple will offer both rental and sales of movies, just like Blockbuster does, but they'll push the rental model, because:
- People don't watch movies over and over like they do songs
- Movies take up a lot of disk space
- People don't want to spend money buying back up drives
- People don't want to spend time burning DVDs
- Renting is cheaper than buying

When senators weigh in on privacy issues like this, they betray their foolishness. A litlle study by their aides would reveal what a non-issue this is. Sen. Franken would do better by investigating our own government's spying on its own citizens under the cover of the Patriot Act.

Why did everyone jump to the conclusion that its offical name is "MacBook Air"?
What is air-like about a small tablet laptop? This is obviously a proliferation on the 'world without wires' concept...
iTunes Rentals ... snatch them out of the thin air to your new AppleTV is much more logical.

Do you remember what the price was for the 1.66GHz CD 1GB RAM 100GB HD?
I think it was $849. I can't recall for sure, but I'm 90% sure it listed as 11% off original price, which is $849. Well, that had a SD in it not a CD.

Technically, it's a manual gearbox... (http://en.wikipedia.org/wiki/Direct-Shift_Gearbox)
It is... or perhaps more specifically semi-manual/semi-automatic of course. Though I think of it as a manual and not an automatic.
If this sounds strange, I had an old Beetle with a stick shift automatic.
The legendary semi-automatic Beetle... they were brilliant, clever for the time. IRS too... which eliminated the normal Beetle's tendency to tuck a wheel during cornering. :eek: :p
