This. Ever since I lost the physical keyboard of the blackberry, I have had to accept to live with a significant and constant productivity hit when it comes to writing more than a couple of words on my touchscreen phones with the need to avoid typing errors. I failed to master the act of writing on a cellphone, contrary to typing on a physical keyboard.

I have seen people type blazingly fast on touchscreen phones though, albeit I didn't run error stats on their output. I accept that I may lack some skills needed to become better at this, but seeing others highlighting that this is a problem to them is not surprising to me, based on anecdotal evidence.

E.g., I knew someone who added to his email signature a permanent apology for typing errors giving the justification that he was typing on a touchscreen device.

All in all, I agree that the problem is real, and havging had experience with a working solution (physical keyboard) I wonder why there appears to be no business case today for such devices.
