please, look more carefully to Mac specs, it uses ECC memory which is 3 times more expensive, here is your 1k difference
You could build a hac for under $1000 that runs circles around a MAC PRO and I am a mac user 99% of the time.
However, ECC memory is server memory, not workstation necessarily, which is Apples way of just ripping of the Pro Users. As well, so aren't the CPU's and still, even with the latest iMac's, while I am happy about the i7, the iMac is very limited, no eSata,2,3,4 drives which all PRO AUDIO and PRO VIDEO users use, and PRO SUMERS which outweigh the pro's like 10,000 to 1, yet Apple still doesn't get it.
Again, Avid did get it, they saw the writting on the wall, they saw CPU's getting faster, and becuase of this, they bought a company called MAUDIO and now make millions in sales with PRO Sumer products. I also almost worked for Steinberg, the makers of Cubase and Nuendo and they said, CP, that they make 1000 times more money in the prosumer division then the PRO division (PRO BEING NUENDO), yet Apple has yet to release a product for the PRO SUMER. The iMac doesn't have eSATA ports, no express ports, heck even the 15" no longer has it, and with PC towers, Mac Pro and 17", you can get what they call plug in cards that have FX like reverb, some costing more then the computer and take all the load of the CPU so you could have hundereds of tracks and some systems now have PCIexpress boxes where you can hook up card after card and attach it to a laptop and use for example, Steinberg VST FX or virtual instruments, taking the load, again, off the CPU so you can load orchestration instruments, samplers, sound design software, and more, not to mention blazing RENDERING speeds, yet Apple only has two products for these kind of things, the PRO and 17" as the imac may have QUAD core but it has ZERO expansion except firewire and if you've ever seen the performance of eSata, it's just as fast as internal.
With the new update, for me as a PRO, it's a love hate relationship. The 17 is to big, the 13 is just right for carrying around, but there is always a gotcha, doing video, which the 13 is perfect for as it's so small, forget about using express cards for two more hard drives in RAID, you can't - it's not "AS IF" its INTENTIONAL, as APPLE marketing is in a way that you have to spend BIG BUCKS to get the machine you need and what's sadder is that Apple fails over and over to realize that just gaming alone, outsells video and music sales, let alone your PRO SUMER market, proven by the last several years of APPLE one to one trainers no longer knowing SHAKE, FCP, LOGIC, it's all iLife and noobs that need to learn how to send an attachment.
Heck one to one and pro care were $100 for both, now they are $200 if you want both. Again, just more slaps in the pro's faces as we kept them afloat for years prior to the iphone and it's things like Pystar that make me happy as this gives some users alternatives as you can buy a case nicer than Apples....for example..

Which is what you would want for audio, especially if you got some of the one's with all the access ports in the front, heck my audio interface and speaker systems cost more than imacs, but still, they have yet to realize,
GAMERS=more sales then music and video combined
ProSumers=sales are 10,000 to 1 in comparison
Enthusiasts'/Overclockers - a very large segment, go to madonion.com if you don't believe me
Pro studios that have macs also have PC rendering farms, far more vaule and these users would buy mid range machines for this purpose.
Another part of marketing is why you will never see DVR on APPLE TV, why, because then you could go to ABC.COM and watch LOST seasons 1,2,3,4 complete vs paying $1,99 to $2.99 per episode at iTunes which ties into why you may never see flash on the iphone, well I have it, even though I am an ATT user and have been for almost 10 years, I have three GV Google phone numbers and ATT now has Alist, you add that number on it and all calls are free, plus of course, flash, tethering, video non 3GS, themes, and so much more. I may even get another soon, call in, say it was lost, cancel the account, then pay the money and switch to someone like Verizon or MetroPCS, $50 flat rate.
Also, thank goodness windows 7 us gettin great reviews as this means millions in sales from IT trickling down to consumers, then if the COURIER is real, wow, especially if its MSFT and not some CHINA 3rd party product, this would be a game changer, shoot, Apple used to make everything in good ole USA, now its all CHINA. Then add all the cool new phones coming look really cool, but a 3GS fast iphone with free calling even on att with tethering thats faster then my wife's moms DSKm I am happy about this.
In closing I am seeing MSFT pulling out some great new products and I hope just like the MSFT commercials caused Apple to lower the prices, that MSFT keeps the pressure on as APPLE is NO LONGER a elitist product anymore anyway, so, its time to make products more reasonable, for example, the AIR is worth $799 tops.
Peace.
