Not parent, but in the comment ancestry.
Yes, as I said, I find typing on a screen difficult and I've put plenty of effort into trying.
To draw a close parallel, dyslexic people have been forced for years to use conventional mass market writing equipment and told that they were stupid for finding that difficult. Mercifully people have stopped doing this. Same applies to left-handers if you want a broad example.
I find this dogmatic "everyone must be the same" and "there's only one way to make a phone / writing tool" quite bizarre and a bit paternalistic. We're not all clones. We don't all have exactly the same needs, or requirements for 'optimum solutions'.
I'm happily typing this on my BlackBerry Passport, which wider than some other people's phones, and sometimes draws comment. But it does the job I need it to so I'm happy.
