Is $200 a good price for an original graphite iBook? My friend has a 366mhz graphite iBook with 192mb ram and 6gb HD. Airport card installed. I want to use OS X on it but I realize it will be slow and consume a large portion of the HD. Any advice for this possible purchase? Anyone know where I can get the 256mb ram chip cheap, as well as at least a 40 or 60gb hard drive replacement? Do you think this is worth the investment for a portable? It seems like a good deal to me.
