I currently use a Logitech Cordless Optical TrackMan with my Mac Mini. Worked great and I have always liked trackballs due to limited desk space required. It has been acting up the last couple of days. New batteries will not help. Reconnecting to the base does not always help. It is just starting to get frustrating. I do not use the Mac Mini very often. I got it originally as my iTunes "server" for my Apple TV. However, I have found it a great companion when doing research for work while I have my work computer doing other things. I have experience with the MBP trackpad since I picked up a new 17" i7 MBP earlier this summer. I really like it a lot. Well, to my question... I have searched and have not found anything which directly compares the Magic Mouse to the Magic Trackpad. Has anyone done a side by side comparison to note which one is more accurate, easier to use, more configurable, etc.? I am looking to get one soon, but want some opinions first. Thanks!
