I'm currently in the process of converting a blueberry clamshell iBook into being a useful mobile laptop. My question is- for what? It's currently running OS 9.1 with 288MB RAM and the stock 3GB hard drive. It has an AirPort card too. This thing is in such pristine condition I can't bear to let it go to waste. I am typing on it now, as a matter of fact. I'm just wondering what to do with it. How much are new or high-capacity batteries? Mine is shot. I'm just uneasy as to what to do with this once my mini arrives-any thoughts?
