Drinking WATER at your PC ??? (soda, yay!)
isn't that like sacrilige ?? heh..
I doubt it's water-proof, but I have an MS Natural Keyboard "Elite". I spilled a bit of diet soda on it once and it seemed to do ok afterwards.
I paid about 17 bucks for it..
only downside is smaller arrow keys.. though I use the keypad so it doesn't bug me
