Hi! I currently have an iBook G4 Power PC, 1.07GHz running OS 10.3.9., 512 RAM its starting to run slow and I getting problems running videos etc as Adobe 10 does not work, along with lots of other upgrades. I also have a problem running a webcam, I've got macam by my Logitech quickcam E2500 is not even recognised. I am a student in UK (studying in France for the summer) and wonder whether i should: 1) upgrade to Tiger 10.4, if so where can I get a copy and whats the best way to do it? 2) go to Leopard ... can I? i'm not sure its compatible. What do you reckon, i'd like to do this as cheaply as possible.
