Das Keyboard

I just read about this fancy computer keyboard on askmetafilter.com and it looks pretty cool.
Plus it has 75 five star reviews, which is kind of crazy for a keyboard.

Do you notice if you have a nice keyboard or not? I guess I like the way some of them click more than others, and I don't like a squishy one, but I can't say I'm really picky.

Maybe I just haven't used the king of keyboards yet.
