Suppose you could buy a one-hand, wearable, computer keyboard that fits in your pocket and lets you type about as fast as, or even faster than, you can type on a regular desktop qwerty. Suppose it has a handy integrated mouse and requires only one hand --- it's operated by the same hand that holds it so you can use it while standing or walking. Suppose it's nicely manufactured and connects to computers, cell phones, game consoles, etc. through USB and/or Bluetooth ports.
