Most people complaining about price are talking about the single processor model, which is "over priced".
Which is why people always compare them to consumer i7 prices.
EEC ram? I've never had it and my videos compress, my 3d models render, my DVDs burn, my Photoshop and Illustrator files work fine. It's a technical advantage that I'd probably want in my server, but don't care about as much, if at all in my workstation.
Any other Xeon "advantage" in a single CPU set-up? No.
Speaking in terms of PERFORMANCE, the single processor models are twice as much due to this i7 v. Xeon issue, and this is SOLEY because Apple choose to go Xeon for these models.
The desktop is dead for most folks, sure, but I have never had an Intel based Mac Pro. My last Apple Desktop was a dual G5 2.0GHz. I've moved my heavy rendering and compressing to my Windows desktops and only use Macs on the laptop side now.
I'm interested in the new single CPU 6 core, but am furious about the 4 ram slots and if the price is truly well above $3500, which it will be since the first thing I'd need to do with the Mac Pro is throw the 3GB of ram in the trash and put all new ram in there, then I'll probably just toss a 980x in my current $1250 i7 12GB ram Windows 7 based build and call it a day.
Why do the ram slots matter so much? Because I'd rather get 12GB or 16GB of ram using the cheaper 2GB sticks. Apple would be forcing me to use 4GB sticks to get above 8GB of RAM.
All we've ever asked for in this Intel Mac Pro world is a $1999 model with 6 or 8 ram slots. The single CPU model comes in the same huge case. Even at $1999 there is PLENTY of profit margin in there for Apple if they would just base the single CPU models on the i7 parts.
I'd love to have a Mac Pro, but have largely reworked my workflow around Mac laptops with Windows computers doing the heavy lifting for rendering and compressing. Looks like that was a wise decision on my part. I'm glad I'm not one of those people who can't "bear the thought" of using a Windows computer, even though Windows 2000 Pro, Windows XP and now Windows 7 have all been fine, stable operating systems. Vista was a bit of dog, but I even give M$ credit for cutting their losses and just dropping it as fast as they could.
