I am interesting in purchasing a laptop from ebay (ugh). I already have a desktop so I really just need something to do while I am on the run or away from home. I was looking to buy a nice PDA but I figure an old laptop would be much better. How are the ibook G3's? I am looking at a 800mhz and a 500mhz. I would really only use it for music/videos/web. No photoshop or anything. Would this suffice and would I be happy with the performance?
