Literally every single MBP in our office has failed, some of them more than once. The failure mode is always the same: the keyboard gets flaky, then you lose a key for a couple hours until you manage to finagle it back into working, then you lose 1-2 more keys and they never work properly again. The only fix is to turn it over to Apple for several days, which means you can't count on a single MBP per employee, because at any given moment --- with near certainty --- someone's laptop will be taken out for several days.
On the plus side, it's a little bit like Chaos Monkey for backups, since you always know you're probably just a day or two away from needing to swap machines.
It sounds like a minor thing, I get it! "Sticking keys, oh no!" The problem is: you can't type. The only way to be typing again on your machine is to have it sent away for several days. That's a disaster.
