It could be cool. I think it is a cool concept to use a lenticular 3D screen in a handheld. I thought Nintendo was going to do that with the DS when I first heard about it.
The only thing I don't understand about this one is that the screen is rotated. The controls don't really match the screen orientation. Lenticular screens are totally directional. If you rotate them 90 degrees the 3D effect is completely lost.
