The hardware certainly does look nice. But I can now say definitively that the Dell will have one big disadvantage: Vista
And I don't mean that in a bashing Windows way. I hadn't used Vista before, and am an XP power user. This Christmas I visited family in NorCal and helped work on 2 of their new computers that had problems with peripherals (all in one printer/scanner/faxes). Both machines had Vista.
I hated it. I hated how it thinks it's smarter than you. I hated how it changed the way to do a lot of things. It was a frustrating 3 hour experience (90 minutes on each PC). Even when XP came out, I realized it was a big upgrade over 98/ME/2000. Vista is, in my opinion, a huge step backwards. And all of the bloatware that these manufacturers put on their PCs, in addition to the bloat of Vista (I mean Vista actually grades your PC's hardware for goodness sakes!) really turned me off.
My desktop PC (an XP machine) that I built 3 years ago is ready to be upgraded. I may build a new XP machine or go with a Mac desktop (Mac Pro or iMac after their next revisions). One thing I am 100% sure of is that I will not be building a Vista machine
I agree with Ron. I'm glad Dell put out this machine, especially with the high-def drive, so that will force Apple to up the ante.
