I have a Powerbook Wallstreet 266 right now. It sucks to say the least. I also have a liquid cooled overclocked AMD with Linux, so the iBook would be a secondary computer. I want to buy one from ebay- probably a 600mhz with DVD or combo drive. I'd just use it for movie watching, web, typing. Would it be fast enough for that kind of stuff, running X? I put X on the wallstreet and it is a total DOG.
