Microsoft Mouse on a Mac Laptop, nice
One of my teachers at my school has an iBook G4 (all the teachers do, the school gave all the teachers iBook G4's about 3 years ago or so), and she uses an MS mouse on it because the touchpad is broken. I've actually used the teacher iBook G4's before (not the one with the broken touchpad, though), and it's a 12 inch like Gil's, and they are QUITE small, especially now I've gotten used to my 15.4" Dell laptop.
