Hello, i just recently bought a iMac G4 in good condition for $175 on Craigslist. I was on a budget so i couldn't afford to spend $1000 on a Macbook I'm not too familiar on Macs since its my first one. But it seems to be a PowerPC, It's running Tiger OS, and the base of the Mac looks like a lamp. I'm sure you guys know what a iMac G4 is . So are there any ways of speeding up this thing ? Is it slow because of its age? Because it seems to be in pretty good shape to me . I did a restore on it and it was still slow. I just need help on improving the performance. Thanks guys. And if you guys do know where i can get a good Mac for under $400 Please tell me . I hear the Unibody thing is the newest kind of Mac .
