I know exactly how to make the best mobile gaming device. You need something more along the lines of a wide Playstation controller with dual-analog sticks on the thumbs. I never understood why they think the buttons need to be facing upward and used only by your thumbs, that's wrong. Your thumbs are the most dexterous and should only be used for analog joysticks. Buttons should be on the backside of the device under each finger so you can press them while gripping the device.
