Re: ibook just came in!!
My guess is that you do have to open the bottom to add more RAM but I wouldn't know, I've never worked that much with an ibook. I do want one though, I've seen them go for pretty cheap and they're actually pretty nice looking and the specs aren't too bad for what I would use it for.
BTW congrats on the purchase!
Desktop: Dell Dimension E510, 2.5GB RAM, Intel P4 3.0GHZ, 250GB HDD, Windows Vista Premium. Might not be the best, but the old girl is still running good.
