I currently have a Powerbook 12 inch, 1 ghz, 256 ram, 40 gig, with Superdrive. Is it worth it to upgrade to iBook 1.33 ghz, 12 inch, 512 ram, and 40 gig HD? For basically next to nothing out of my pocket?
It could be. However, just an increase in RAM (whether that be in the iBook or PowerBook) will massively help. Aim for 1GB if possible for the optimum system performance.
