That is an awful, awful design, possibly the worst designed portable/pocket device I've ever seen. It's like they just got a load of mobile device design options and threw them together at random, without any thought for how they would work in one unit.

The keypad makes the device physically larger while restricting how big the screen can be.

The keypad is positioned really stupidly, in such a way that it would be difficult to operate with one hand. The whole point of keypads on mobile devices is to let you enter text or numbers with one hand, but that has been completely ignored by this design.

The keypad also makes it difficult to reach the screen with your right thumb if you're holding it in two hands.

And because it's numerical it won't help with software that requires QWERTY.

It's got a touchscreen, why didn't they just use a virtual keypad and keyboard? That would have let them extend the screen or shrink the device, and would have made access to the screen easier...
