How the heck are you going to enter text?
As unexciting as it might be, text entry is still a huge part of the way we interact with our computers. The iPhone has relaxed that dependence somewhat—after all, we spend most of our time tapping, flicking, and pinching—but even it can’t escape the old QWERTY keyboard, even if it is merely virtual. But we need it for sending text messages, writing e-mails, even entering our login credentials on Twitter or our mobile banking site.
Indeed.
