After years of wanting one to play with, finally the skies parted and I got a number of G3 and G4 ibooks the last few months. The Pismos were getting a little slow for web activity. So now have several 500s, 800s and two 1.33ghz G4 models. All are running well and I have a mix of old and new batteries. Really like using them as my carryaround notebooks now. I miss the Pismos larger screen and keyboard, but can now mix and match as I please. Another plus is being able to get new batteries for about $13, while the Pismo batteries have recently gone sky-high. Just wanted to share.
