The devices themselves have a finite lifetime. As long as the switch outlives the projected time to obsolescence of the device, it's fine. And I know there are switches out there which can do that...
What really irks me (and what I'm surprised to see so few people spell out) is that there's no tactile feedback on capacitive buttons (or microwave-like buttons). Tactile feedback makes every aspect of the UI profoundly better.
(Tactile feedback is possible on capacitive buttons... the first company which brings capacitive touchscreens with tactile feedback to market will make it huge (and the recent huge investment from Apple may have been into that technology). But no one has come out with a decent implementation yet...)
I thought you were going to say an electric shock. Although an electric shock would also use a lot of power and probably be a terrible idea just like microwave heating of the skin, at least the shock would provide fast feedback
