hi ... i am trying to help my aunt buy an ibook. she'll use it primarily for email, web, iphoto and itunes. no real heavy lifting. what would be the "slowest" model that would suffice. she'll probably buy tiger to put on it and have to bump the ram. does tiger need a g4 to run smoothly, or could she get by with a g3? and if a g3 would be ok, how far back can she go, g3 900, 800, etc. smalldog has a 12" g3 900 combo with 384 megs of ram for $659. on the other hand, there's been refurbished ibook g4 1.0 for i think for $799 at various times. i'd like to find one with an airport card already installed if possible. thanks for the help.
