My keyboard died and we had one of those stuffed in a drawer so it's what got plugged in. I hate it. Maybe you can just rinse it under a tap if you spill your coffee on it but hell, it's not worth all the keys you mistakenly hit and all the others you didn't tap hard enough for the keyboard to register. Too much work.
Yes, roll up keyboards look cool and funky but yes, they are a frustrating piece of crap.
