Anyway, I have had a chance to see it's usefulness on some of the early CoolReader 3 for Android releases. Some of those early versions of CoolReader would hang on opening a book, and the touch screen controls would become unresponsive. I just had to tap the physical "Home" button to get back the central window and then use Advanced Task Manager to kill the runaway CoolReader 3 application.

I don't have an Android smartphone, just Dell Streak and Samsung Galaxy Tab. Both are almost identical, they only have capacitive buttons. Samsung Galaxy Tab adds a very useful "search" button to the 3 buttons (home, back, menu) from Dell Streak.
Capacitive buttons, as you describe as well, totally rely on the OS. If the OS struggles, they aren't responsive.
Maybe I've used the wrong term. By "physical button", I've meant a button which has to be pressed mechanically, whereas the capacitive buttons react on a slight touch (touch = power consumption = relying on OS).
