As the title suggests, how well/bad will Photoshop run on a PowerBook? I have a P4 2.4ghz with 512 333mhz laptop that doesn't handle Photoshop very well so naturally I'm hesitant that a Mac 1.5 G4 with 512 will perform any better with it. Can a PowerBook take more than 512 of RAM? I know the major problem with my laptop is the slow (333mhz) memory and being limited to only 512 which barely qualifies as a decent amount but laptops aren't really designed for power. I know the obvious solution is to get a Desktop but I already have 3 PCs in the house (my gaming box, one running Linux and my daughters computer) so I really have nowhere to put another desktop and I want portablility. Now, I must admit, the only reason I am considering getting a Mac is for graphics. I already know Photoshop and Illustrator but many places also want knowledge of Quark and Macs in general. So would getting a PowerBook for graphics be pointless? Thank you for any help.
