The wireless mouse is working perfectly. It took just a few minutes to trust it and get used to the feel. Just like scrolling on an iPhone or other touch screen device. No issues to report. I have mine programmed for right click and for dashboard and a few other things. All working great. Much more comfortable than using the track ball. I will say that at first I didn't want to rest my hand on the surface for fear that it detect movement, but that tendency goes away after a little time. It is a very sleek design as well.I'm wondering the same thing too, but I haven't heard one complaint yet from the new iMac crowd. Is the wireless keyboard/mouse working perfectly?

By the way, my 88 year old neighbor came to see my new Mac and he fell in love with it. I drove him to the store and he bought one yesterday. One of the reasons he liked it was because he has arthritis and can now work the mouse with ease. So, this is a big bonus for him and his wife (both in their 80's and going strong!).
