After four logic boards and two hard drives, Apple has decided that my iBook needs replacement. Not bad, I'm getting a 1.33GHz model to replace my 2.5 year old 700MHz model. Anyway, I'm wondering if I'll ever notice the difference between 768MB and 1GB of RAM. My guess is no because I don't really use any heavy duty software. Also, if anybody needs an AirPort card or a 512MB stick of Crucial memory for a G3 iBook, then let me know. I'll let 'em go fairly cheap.
