If you don't like typing on a touchscreen, you are not alone. There is no physical feedback, you might hit the wrong key, and you leave fingerprints and oil all over the screen. You might even have mobility issues that present a challenge.
Those were the concerns of the inventor of the txtRng ;) which is finger ring with a stylus 'nib' attached. You can wear one or two on your thumbs and text, email, type, etc. It is a nifty gadget that might even help you with your gaming, besides those legitimate needs mentioned earlier.
