Not really. Tons of people, myself included, use the crap out of mobile phones. I had to do real work to get good at Android. And I am. Can do amazing things on my picture behind glass thingy. Of course mine comes with a pen. Made some tasks possible and practical. That said, I pretty much hate it. The thing demands a lot of attention. My older tactile device didn't. Like the other comment says, tactile interfaces can be used in pockets, etc... I do not know what the future holds, but leaving grease smears on a touch screen probably is not it.
