a RIM spokesperson has now confirmed that the first device to run BlackBerry 10 will not have a hardware keyboard.
Then RIM CEO Mike Lazaridis in 2007:
Try typing a web key on a touch screen on an iPhone, that’s a real challenge. You cannot see what you type. (…) The iPhone has severe limitations when it comes to effortless typing. Of course you have more screen space, with more artistic interactions, but that’s not enough.
Seems enough now.
