It has a vertical screen because it's a cell phone... all cell phones have vertical screens. What the N-gage needs is a design that fits to this type of screen, maybe one like an original Gameboy Color was or something. The current design they are using really isn't meant for vertical screened devices, only widescreen ones. I see unused space next to and around the screen, but there really is no place for the screen to expand unless it has a lot of room above and below the screen, thus, the n-gage 2 would be much better suited to a vertical design to fit its vertical screen
