Oh, you will get used to it, if it's a good quality keyboard.
   You use your thumbs. I first experienced a keyboard like that
   back in 2000 for a palm Pilot I had ("thumboard' is what they
   called it). Within two weeks, I was typing with my thumbs at 30
   wpm and 95% accuracy, which is pretty good. (I type 110wpm on a
   computer keyboard) - I like the tactile feedback on the thumbs.
   But you can also set an android up to vibrate or beep when you
   hit the flat virtual keyboard, which might work for you. you
   really need to spend an hour with it and try to do everyday
   tasks on it. "
