I have an iBook G3 refurb on its way, should be coming Saturday. My question is about the RAM though. It's a 900mhz G3 with 256mb RAM, and 40gb HDD. It's going to be running OS X 10.3. For now I only plan to run iTunes and internet, e-mail, light stuff. I plan to max it at 640mb soon, but not right now. You think for the time being that 256mb should be enough for my iTunes and smaller things? Eventually I want to use iMovie and some other things, but by than I should be at 640. So, basically I'm just asking if at 256mb, will it still be sufficent enough to run those apps smoothly for say maybe a week or two before I get the 512 stick? Thanks.
