I agree with you. But I think the touch pad is a harbinger of things to come. The eventual goal is probably a touch pad keyboard, one that reconfigures depending on the circumstances. It might even be like the Star Trek NG consoles eventually. I think it might be possible to use the haptic touch on a localized level such that each key press causes a sense of typing feedback.
And the good news is .... you don't have to!
I have absolutely 0 desire to use a tiny strip of touch above a perfectly good keyboard.
