I recently sold my iBook G3 600mhz/Combo to a friend. It was a great computer and I don't really have any complaints. I want to step up to a G4 so I can run GarageBand and similar programs to use my computer to write songs (guitar/bass/etc). I was all set to get the new 12" G4/1ghz/combo iBook (and record via iMic) when I came across the closeout 12" G4/1 ghz/combo PowerBook for about 250 dollars more (I checked specs on both at MacMall too). I know that the specs are very similar. The Pbook has audio in and a better graphics card and monitor. The iBook has USB 2 ports and a lower price. A good friend with lots of knowledge said to just get the iBook, but I don't know. Any advice would be appreciated. Thanks!
