Talking of hacks, I've also just found a cool commercial product that's a cool hack on the Magic Trackpad.

The Magic Trackpad is a terrific input device though I find that placing it next to the Apple Keyboard -- which is what looks like the elegant way to arrange these devices -- is, at least for me, a recipe for disaster as my large, clumsy hands occasionally brush the Trackpad resulting in unexpected and annoying relocations of the mouse. I now keep the Trackpad separate from the keyboard which makes finger fumbling mistakes far less likely.

A product I found, the , makes the Magic Trackpad much more useful by adding new functionality to it.

The Magic Numpad consists of an OS X application as well as three plastic overlays that fit exactly over the top surface of the Magic Trackpad. Each overlay has a different layout of "pads" that act as virtual keys and are mapped to various functions so you choose the one that best suits your workflows.

An application that you download from Mobee's Web site handles the mapping of touches on the Trackpad virtual keys to the execution of the virtual key functions. You enable "numpad mode" through the Mobee application that lives in the system bar.
