The engineering & tolerances to make a typical microswitch (what makes the pushbutton actually do anything) would make most peoples eyes water. (from boredom, perhaps...)
Fun fact - if you engineer the people facing mechanism to keep the switch pin from being depressed all the way flush to the switch housing, the lifetime of the switch increases by roughly a factor of 10. A 0.1 mm difference in pushbutton throw is the difference between getting maybe a million cycles, say 3 ~ 4 years of constant use, and the switch outlasting everything else in the product.

Mechanical keyswitches have some pretty amazing reliability though. I actually like the touchscreen everything movement in most applications, partly because of this. A screen may be expensive, but good switches might be just as expensive.
