I am looking for a wireless mouse for my PowerBook and I am wondering abot one thing. If I were to buy a bluetooth mouse like this one http://www.logitech.com/index.cfm/products/details/US/EN,CRID=2135,CONTENTID=7110 Would I need to use their bluetooth base station? Or can I use one without connecting it to my notebook? Basically I am looking for one that I don't need to plug in a receiver onto my laptop. Also, do you have any suggestions for good wireless mouse?
