I'd been saying for two years now that phones should have its buttons up top and the screen below it, since most people cradle their phones in their palms. In order to type on a phone like the RAZR, you'd need to balance it in with your fingertips.
Finally, Wildseed has the first phone I've seen with this form factor. Admittingly, it looks a little bit odd, since it looks like it was bent quizzingly. But it should fit better from a usability point of view. Form over function!
