Really? All the time I've watch elder people operating devices
I found they were completely puzzled (or at least slightly
annoyed) by the conceptional (and physical) gap between
an unlabelled physical button (a.k.a softkey) and a label on
a screen describing its current function.

In my opinion it's a matter of a coherent UI. It's certainly
more challenging to get to a good touchscreen UI, but if you
have one, I believe that usability can be more efficient than
one a hardkey/non-ts UI.

Also, I'm not buying the redundancy argument. In my opinion
more ways to achieve the same (i.e. by accessing functions
through hard buttons, through soft-buttons, and through
browsing menus) is more confusing than having just one way
to trigger each and every function.
