I'm toying with the idea of making a smallish dedicated keypad with keys for the most commonly used functions. I would then mount the keypad in a optimum location within easy reach. I Prefer real buttons to a keyboard or a touchscreen. I would design it so the buttons could be easily re-assigned. Do you think this idea has any merit? If you had such a device what buttons would you like to have? For anyone using a touch screen, does it work well or are the smaller buttons too finicky to select?
