My sister is looking into getting an Apple notebook and plans to be doing a lot of work with Photoshop and Quark. She is by no means a professional but needs to at least run these programs at a reasonable speed. I suggested the PB over the iBook for a few reasons (G4, Altivec). If she gets a PB, will the 12" be enough for work with graphics? My biggest concern in recommending the 12" is the small screen, but since I've never used it before, I'm not really in a position to pass judgement.
