Well, I was at one point, so set on getting a new 2010 Mac Pro, but I've pretty much made up my mind that I will be waiting for the new 2010 iMac i7.
All the glum pricing talk here has ultimately swayed me over. I simply cannot justify the price of a Mac Pro (considering they continue the current pricing trends...) vs. an iMac i7 with that gorgeous 27" display.
I've priced a low end Mac Pro with an inferior compared display to over $3000. I can just find so many uses for the extra $1000 if i go iMac.
But I promised myself to at least take a close look at the new Mac Pros when they do come out, just to see my options again. But yea, I had that anticipation before, but it's all directed for an iMac now.
Edit: Btw, I am an avid ebay seller, so I have no problem in selling older machines for newer models. And due to their simplicity, iMacs are just so much easier to pack up and ship, rather than shipping lumbering towers while detailing every single upgrade and component to the buyer. Some people that are pro-Mac Pro like to argue about it's versatility as an upgradeable tower, which is a definite plus, don't get me wrong, but personally I have no problem living by with keeping an iMac for 3 years until Apple Care runs out and then painlessly selling it to refresh the entire system.
