I can barely manage 20wpm on my phone, and that's on a good day; the next-keystroke prediction and autocorrect both fail so often that I spend as much or more time correcting text as I do entering it. Meanwhile, I easily hit 120wpm when typing on a real keyboard.

Typing on a phone feels like having both thumbs tied together behind my back, with one finger broken. One reason why I'm so excited by the Gemini PDA is that it might not feel that way.
