I am searching for a good and cheap usb-mouse for my first mac, ibook . The Logitech models are attracting my attention and they have many good models. Any other options, Microsoft? The mouse should be priced around 25-40 and cordless.. The thing that is bothering me is that the system requirements are odd. The models I have been looking for seem to support only up to Mac OS X version 10.3.5. Do they work with Tiger 10.4 even though it isnt mentioned there? Thanks for your answers! Any help wanted ..
