I have one of these provided by my employer - spacebar broke within a couple of months. Also, I kid you not, the 'H' key was not functioning on one in the Regent Street Apple store I was using while waiting for an iPhone battery replacement. Essentially, you have to avoid getting any detritus on the keyboard of any kind. I no longer eat any snacks or sandwiches at the computer, which is probably a good thing anyway.
