Furry keyboards

If you share your office space with anything that sheds (cat, dog, yourself) you'll love this keyboard: 

Logitech washable keyboard

Not so much for dunking it under a faucet (haven't tried that yet), but because the design makes it so easy to remove fur from between the keys. Just run a Q-tip between the rows of keys, and it will pick up most, if not all, of the fur.

Bonus feature: for those occasions when  you really need to see the keys (like searching for an odd symbol on top of the number keys, or first thing in the morning before you're awake, when you need to put in your password while leaning over the desk, not really in a position for touch-typing), the white keys are so much easier to read than most other color combinations.
