I want to purchase a Cordless mouse which I can use with my Macbook OS X which I have recently purchased and still learning what Mac is all about. I have been wading through the Logitech Site and the two above seem to be what I am looking for. I would like it to run on wireless if possible. But one mentions Blue Tooth Wireless which I do not understand fully. My internet connection is Wireless on my PC which I pick up on my Laptop? Question is has anybody used either of the above and have any comments on how they got on with either, or any other mouse that would fit my requirements. This is going to be a Christmas Present from my Husband so price is not too important. (hopefullY)
