If you use the keyboard a lot, give yourself the ultimate typist's keyboard, the Avant Stellar.
http://www.cvtinc.com/products/keyboards/menu.htm
Programmable 116 key design (inc. macros), heavy-guage steel, proper mechanical click/tactile key switches (almost sounds like a typewriter if any of you can remember such things).
Solid as a rock and weighs about as much (doesn't wander around your desktop) and a real pleasure to use - puts all those gummy soft key things to shame.
Keys that fight back! I love it.
