Hey everyone, I've convinced my best friend, who has been drooling over my 15" Powerbook, to ditch her aging PC and get a Mac. The only question now is what model she should buy. I've been using my 15"PBook primarily (but not exclusively) as a desktop replacement. She, on the other hand, tends to be on the road a bit more, and will probably do a good deal of work (Word, Excel, etc) while travelling. She's tempted by the portability of the 12" PBook, but wants more screen space when she's at home. She (and I, because I'm her primary source of Mac-related information) have been going back and forth the 15" and a 12" with a flat screen display (probably a 17", though not necessarily from Apple) for home. Anyone else been in this situation? If so, what decision did you make and why? Thanks in advance!
