the most obvious immediate solution will be for me to pick up a usb keyboard, but i should also be able to replace just the top on this item fairly easily. to the engineers' credit, it actually seems to have been designed to localize the effects of spills on the keyboard. so, the keyboard may be fried, but the rest of the device seems fine - and the keyboard can be fixed for about $30. don't spill water on your computers.
for right now typing is going to be somewhat annoying for a while.
