Split Cell Phone?

Hah! I just saw an ad for a new cell phone here in Japan. Apparently it splits -- into the screen part and the keypad part? So you can put the screen up high and play with the keypad down low (for games, etc.) That's a great idea -- split the monitor from the input. And I predict the next step will be to let it tie into the TV or whatever is nearby, right, so that you can use the bigger monitor if available. Nice...
