I was actually warned by the Apple Store when I got it how fragile the keyboard is and that if even small amounts of stuff got on the keyboard it would interfere with the keys due to the lack of any space below the key cap.
It's not quite the same keyboard, though it is similar. Time will tell how it holds up in comparison, though.
I actually quite like typing on this keyboard, although it was weird at first, but I wonder how these things are going to hold up.
