If you all have not had a chance to try Apple's new Trackpad, go to any Apple Store near you, of course if there is one and give it a try. I just bought one for use on the Macbook Pro mid 2010. It's absolutely fantastic. Though it requires you to be running 10.6.4 and that you have bluetooth available on your computer. The bigger working space on it, is so nice to have available to you. If you do buy one you will also need to get the latest Trackpad update software, as it requires it for better operations.
