You know, laptops with a pen input have been around for a long while. Even the convertible kind. I don't think that form factor is fully baked yet. In fact, I have a couple of HP tc1100s from the year 2000. You can still get good use out of them. But as a mass consumer device, they were not a runaway hit.

I suspect that Apple has a roadmap for conservatively rolling out more digitally configurable/reactive/touch interfaces on their laptop form factor. They will do this while working off the of strengths of each input device. My bet is that they will come out with e-ink keyboards and some kind of display built into the touchpad, perhaps with a stylus.

I would concur with you that this was a disappointing Mac event, however.
