Unrelated to the thread but for RSI I found the patu forearm rests to be a life saver. They work by suspending the tendons responsible for hand/finger movement in air while your arm weight rests towards your elbow or the fat of the forearm. After using them for a month my hand pains were completely gone.

The way desks are made is actually horrible for your hands and RSI because the tendons responsible for hand and finger movement run down your forearm. When you rest your palm or wrist against a desk you are limiting their movement while demanding motion. This is very damaging. This can also be done by using a vertical mouse which forces your fat side of the forearm down instead of the tendon side.
