I've been using DOS and Windows for all my life and I've finally decided that I'm gonna switch to an iBook G4 (or G3) just as soon as a good deal comes up on eBay . I've just got a few questions before I buy. 1. I've currently got a Windows XP PC with a 512kbps ADSL connection. Is it possible to set up an iBook to wirelessly share it's connection? I know nothing about wireless stuff. 2. If when I buy an iBook it doesnt have a DVD/CD-RW combo drive in it, would it be possible to put one in? 3. What sort of spec. should I be looking for? I will mainly use it for: Getting music from a CD to my iPod, DVD playback, school work (mainly word processing and maybe a few presentations), web based e-mail (gmail), web browsing and maybe using iLife.
