The first thing that I see is that if I try to configure TODAY using this HP and the Mac Pro I'm comparing an i7 Xenon based Mac Pro against a Core2 based HP. If I were honestly shopping for preconfig systems with HP and that was my model, I would be considering an iMac on the Apple side. Again, I'm typing this on my Vista64 based i7 machine...
And again, MobileMe? That accounts for like $750 and if I didn't use it to keep my iPhone in sync with my gear I wouldn't have it... And BTW I'm using MobileMe on my Windows PCs. One on one care gives the ability to schedule 1:1 hands-on training in an Apple Store. That's what it is.... why was this added? The whole thing is silly.
Err Xeon... wish I could edit.
I'm not sure how you say the Mac line has barely been updated in the last few months when its had a complete overhaul to the new processor architecture.
