"Cracked button" really doesn't seem like a realistic issue. And they really don't fall off easily. You're free to have your preferences but the reality is still that most physical buttons are incomparably more durable than a touchscreen, especially a large one, especially if it still happens to be a consumer grade laptop screen. Simplicity has its benefits.

And if/when the buttons crack/fall-off there's a very good chance that you can fix it there and then with a drop of super-glue. Try that with fancy touchscreen...
