After reading this thread plus some of the reviews on the Apple store I picked one up yesterday. The Magic Mouse is now packed away.

I had no real problem with the Magic Mouse other than a lack of space on the computer desk. The Magic Trackpad takes up much less space when in use and does more than the mouse. All in all an excellent piece of kit.

I seem to have generated quite a bit of revenue for Apple with this thread. I'll be waiting on my cheque.

Thanks for all the replies. I'm going to get one ordered.
