You really have to be unlucky or do something stupid to bend the keys. You just have to pick up the CPU and put it back down at some place without any pressure. If you let it fall down or try to force it to go somewhere - sure you can kill it. But how often do you let something fall down every day? For me it's the same probability then damaging my car while parking in a spacious parking lot - which will be even more costly. Or dropping my laptop.
