I mean yes, of course, but how could it be otherwise? A desktop keyboard is 10x the size of an entire mobile phone. The idea that it should somehow be possible to attain the typing performance provided by such a large dedicated input device on a phone the size of a keyboard's space bar is pretty ridiculous.

And I'm unconvinced that the "Eloquent" design presented in the article is a step forward. The "T-Menu" looks terrible and confusing, and I find the drag animations quite jarring.

The only obvious, intuitive mobile interface for text entry is speech-to-text. I know it isn't quite there yet, but that doesn't mean fiddling with details of how cursor movement works on a phone screen has any realistic chance of ever solving the problem.
