The alphabet has been around for even longer though. QWERTY, along with key staggering, seems to be useful for backwards compatibility with typewriters, or perhaps with those who learned on backwards-compatible computer keyboards, but this keyboard isn't close to that of a typewriter either way, not likely to be used any similarly. And I suspect that random people on a street are more likely to know the alphabet, rather than the QWERTY layout. The screen indeed looks like it'd be tricky and annoying to read.
