This is a cool post! I think that the Magic Trackpad is worth owning, and it makes it a pleasure to use the Mac. Unfortunately, it can bug out sometimes. Usually, this is because the battery is running low. It starts to happen after a few hours of continuous use, when the battery life approaches 50%. I wrote up a how-to guide on my site, Appledystopia, for troubleshooting and fixing it. There are some neat tips, like adding it as a Bluetooth Favorite, so if it loses the connection or you toggle the power, it will connect much faster.
