I put in an order for a MacBook last week (Macrumors says the time is right)! And I'm too cheap to buy MS Office so I'm thinking of trying to use OpenOffice.org for a while until my incompatibility forces me to cough up the dough.
The reasons for the switch: digital videocamera and more digital media handling, and needed a laptop. I'm still going to use my Dell desktop rather heavily, but I've already starting deleting music files from its choked 60 Gig HD (Sixty gigs! Unfillable , it seemed). Multi-platform, baby! I hope this helps with some of the incompatibility issues I occasionally get with documents from WGBH.
Mac users, I need help: I didn't get Apple care for the machine but I have up to a year from purchase. Pete said he's never had to use it. Although I think Andrew had problems with his Macbook. Comments are needed! Is Applecare worth getting? ($249 for three years -- have you spent more than that for Mac repairs?)
