The main point is always worth reiterating (take care of your body), but before a bunch of people run out and buy wrist supports I just want to add that things like this are not universally endorsed by physical therapists (or fellow injury-prone hackers). They can lead to secondary issues like atrophy and poor circulation, which in turn lead to more issues, etc.
Having been through multiple versions of these (the kind he has, less restrictive ones, custom-molded ones), I found my body held up best when I kept it active and strong on its own. The term "crutch" has a double meaning in the English language for a reason: sometimes it's truly necessary, but when it's not truly necessary it's actually hurting you in the long run.
It's worse, actually. Last I remember reading the whole idea of keyboard-induced RSI is basically a myth. For RSI sufferers, keyboard use irritates the problem to the point where it can be debilitating. But there is no known correlation between keyboard use and RSI.
Some people have wrist pain, some (like me, despite living full time at a keyboard for most of the last 20 years) don't. If you do, take care of yourself. But don't do stuff like this prophylacticly, it's more likely to hurt than help.
This. It should be pointed out that we already have 'wrist support' built in. It's called tendons and ligaments. Center a workout around heavy deadlifts twice per week, and these support structures are guaranteed to strengthen, along with the rest of the body.
