Hi, I have a PowerPC G4 that I bought in 2001. The hard drive died, and I bought two new hard drives in the past year. I'm beginning to think my user habits are too much for this computer. I often am using video editing software at the same time as a brower, iPhoto, Microsoft Word and Adobe inDesign. So, I was thinking of either getting a Macbook Pro, or the iMac. Which do you recommend? I don't carry my Mac around with me all the time, so I don't really need a laptop, although it would be handy. Also, if any of you out there are G4 users, are you getting boinking sounds every so often, and the computer automatically types zeros when you don't want it to? Like this0000000.
