As reported in an earlier post, I received an Apple Magic TrackPad about one month ago. At that time, I replaced the existing Magic Mouse, now relegated to a drawer in my desk.
I must say that I give the TrackPad a 4.5 out of 5. My greatest complaint at this point is the definite slice I have developed when playing Tiger Woods PGA 2008. The multi-touch capabilities are very similar to the current trackpads available on the MacBookPro lineup, but with a larger surface for your fingers to wander.
One multi-touch action which I tried, but disabled was the One Finger tap for a single mouse click. I found myself clicking inadvertently as I used the device. I, instead, used to manual click for that feature.
Battery life appears to be viable. After one month of constant use, the battery is holding at 60 percent.
Overall, I am very satisfied with my purchase and would certainly recommend the Magic TrackPad for other Mac users.
