How long would a new iBook last? Are Pentium M's (future for iBook) a lot better than the 1.33 Ghz G4s? How are they better? How long would it take for a complete transition( no bugs and all apps on Intel)? I ask these questions because I will NEED my own laptop in around 2009, 10, and 11 but I WANT one now. Should I wait a few years for the "better" Intels or buy one now and it will last me.
