Hi all, I just upgraded my powerbook 1.5ghz g4 to 2 gb of ram. It runs multiply applications fine now. The only thing that I'm still disappointed with is when I am viewing videos on youtube or elsewhere my CPU maxes out and the video is all chopping. I know it's old (6 years!) and I need a new computer (which I'm thinking of getting the 27" iMac i5) but I feel as if it should be able to view videos on youtube without being chopping and maxing out the CPU... Does anyone have any suggestions on what I can do (other than buying a new one)? Thanks!
