Microsoft Shift

With all the touchscreen fanaticism that occurred over the Apple iPhone, it is no surprise that Microsoft has come out with a product that is very touchy-feely.
Microsoft's Shift (working title) is like a GPS/Mapquest device that only requires a finger interface. It is designed so the user puts his/her finger or thumb down on one location, then lifts his/her digit to select the next target.
I guess user-friendly doesn't get any simpler than that. Of course, it might be difficult to use this on a tiny PDA or cellphone screen. Some ideas sound good, but the actual development reveals all kinds of complications. Let's see if that happens with the Shift.
