Putting the desktop into the mobile

On a recent trip to NYC I had the opportunity to drop by the flagship Samsung store in the glitzy Time Warner mall near central park. The store shows a variety of products ranging from cell phones to TVs. There is a remarkable amount of experimentation shown in their cell phones which range from rounded cameras with phones in them to full transformer-phones with rotating keyboards. One of the less fruitful mutations likely to go the way of the dodo is pictured below. It is a windows mobile phone with a joystick/mouse. Imagine trying to position a cursor over that lovely windows "Start" button while walking - or even standing in their store trying to demo it for that matter. It seems like a simple usability test would have kicked this one out of the running - but from what I hear they typically don't do that sort of thing.

The black square at the bottom is a joystick that supports scrolling around the entire screen before pressing it to click a desired object.
