I can never go back to the "click-click-click"ing of a real keypad/keyboard on a phone. My thumbs can fly across a touchscreen keyboard and send out a text before anyone realizes I have my phone out.
I have a hard time thinking they can take on Blackberry with a this. This is the area where Blackberry actually dominates, though the market is a bit smaller today for it. Best of luck competing with the Q10.
