Ok, so I have the final revision iBook G4 12" 1.33Ghz (it was purchased in feb 06, I bought it used in november 06). Right now I only have the stock 40GB hard drive and 1GB of ram. I'd like to max out the ram (I think the limit is 1.5GB) and also add more hard drive space. However, I'm not sure which type of hard drive I need for it. I'll be ordering whatever I decide on off of newegg. Any advice?
