That's a hack that doesn't work very consistently. For example in most terminal emulators or the Google Docs app Alt-Tab does nothing. In the Browser the first press of Alt-Tab will just put the focus on the url bar, and you need to press a second time to get the task switcher. An inconsistent mechanism is even less useful than a cumbersome one. However, it also looks as if some update has also added the capacity to navigate the recent apps menu with the keyboard, which is nice. It still needs to be triggered from the touch screen, but it's getting there.
