i'm a longtime Mac user who has never had the need for a laptop until now. (my primary machine is a G5.) for my work, i'll soon be traveling to some rough places (doing work with landmine recovery) and i'll need a laptop for word processing to write reports. i don't want to spend the $$$ on a new Macbook -- i'm working under the assumption that the computer could be manhandled, covered in dust and grime, or dropped in a swampy river. i'll be using it primarily for Word, iTunes, iPhoto, and wifi. (no Photoshop or InDesign or other memory hogs, and i don't need a DVD player). i've come up with some options: 1. get an older generation, refurbished ibook (can anyone suggest reputable dealers and the going rates?) 2. i know this is sacreligious -- get a cheap (not exactly throwaway, but not high-end, either) PC are there any other options? if i go with a PC, i'm not thrilled with platform switching, but since i'll only be transferring Word files, it shouldn't be a problem. also, are there compatibility issues with syncing my ipod to both my G5 AND iTunes on a PC? thanks.
