New Scientist reports on a good problem:

Although touch screens are growing in popularity with designers, tapping at images of buttons on a small, slippery surface does not provide a good user experience. Figuring out better ways to input text on touch screens is important for more than just phones too, as they become common in other places like desktop computers, gaming devices and coffee tables.

The solutions offered are very disappointing, because they don't address the core of the problem.
