I've got a G3-800 iBook with 128MB of RAM, running OSX 10.3. The iBook runs well, though slow, and I'm wondering if people think adding 256MB (bringing it to 384) would be a worthwhile investment. I can get a 256MB SODIMM for <$70. I only use the iBook for simple web browsing and word processing w/Word. What do you think... worth it?
