What an incredible Christmas gift. A thing of beauty. Am I going to regret it if I don't exchange it for the upcoming Penryn? Will the lifespan of the Penryn be so much greater? These things (2.66 Xeon MPs) are so reliable, quiet and beautiful. I do some video rendering and a fair amount of CS3, but most of my time is spent writing and doing the usual webstuff, iTunes, email. She got if for me primarily to drive my ACD 30" and I must say that they make a handsome pair. Does anybody want to talk me into returning it for a Jan. 14 purchase? Does anybody want to talk me into keeping this? It is GORGEOUS!
