Maybe that's why Apple is pushing for voice recognition with Siri.
I still think people like big screens on smartphones and thumbs be damned plus nobody seems to like voice recognition or Dragon Dictate would be on every PC.
People like voice recognition, but its uses are limited. I use voice search on my Android phone every time I get in the car to go somewhere that I need navigation to, or if I need a map. That's about it, though; having conversations with your phone makes you look rather special.
