Speaking of keyboards, the Microsoft Natural Ergonomic Keyboard 4000 is the Cadillac of input devices.

Featuring a split design with angled keys and a cushioned palm rest, the 4000 is built to keep the user having natural hand, wrist, and forearm position. It might be gigantic and ugly, but if you’re serious about keeping RSI away (or are already fighting it), this $30 might be money well spent.
