text: windows or mac?   mac os x 10.4.5 ("tiger"). i have an imac g5. it's definitely a lot better than a pc, it has built-in wireless lan (airport), bluetooth, and speakers. it's also a monitor and computer in one box instead of a monitor plus a big box.  g5's are definitely faster than celeron 1.8 ghz machines, which i previously had. since many of the computer manufacturers still sell celerons as low-end computers, i just figured i would let you know.
