actually you can upgrade an imac...yes even the G4s..I've done it...plus macs are so incredibly easier to use than pc and take up so much less space and look so much cooler...and I found a software that allows you to play PC games on mac os...ony 60$ plus had like 10 games...or you could pirate virtualPC for free
and the cost factor...I've found that imacs are the cheapest computer around....try to build a superdrive G4 imac comparable computer on any PC site, i.e. dell, gateway, and it'll cost you around 1,000$ more
