My current laptop is a 500 MHz iBook G3 Dual USB, the oldest model that it's still possible to buy batteries for (not accidental). It has 320 MB of memory and a 10 GB hard drive. I like it because I can get over 6 hours of battery life from the thing, well over what Apple's specs show. However, I have it running Tiger, and it's obviously a little slow. What I'm wondering is if I should spend the $70 or so to max out the memory and maybe replace the hard drive before that dies. Will it perform significantly better than it does now on 576 MB of memory, or will the processor and graphics card just slow things down? I don't need to do anything fancy, just get online and take notes, maybe run Coda, but it's pretty sluggish for that. I'd like to be able to run Pages rather than having to take notes in TextEdit.
