You can use pretty much any USB mouse in a mac. Microsoft has mac intellipoint drivers as does logitech and others. My Dad upgraded to a Mac G4 400 and i gave him my MS wheel mouse. He loves the flexibility.

Many years ago when 486s where the latest PC CPU, the company i worked for had laptops with docking stations that took ISA cards. Just as well as there was no other way to get them on the network!
