I bought a Macally iopti jr usb optical mouse for my ibook2. It has 2
buttons and a scroll wheel and the scroll wheel functions as the middle
button too. It works great in Mac OS X (beta software for customizing
buttons available) and YDL 2.1 picked it up with a 2.2 kernel and the
benh 2.4 kernel picked it up as well. Not only that but it is hot
swapable in linux and Mac OS X! It is small. Have fun.
