I used to have a Blackberry Pearl which had a seemingly unique keyboard layout of two characters per key. It was the perfect compromise between the old school T9 and qwerty. That keyboard (with physical keys nonetheless) combined with that little trackball thing, it was easily the best handheld device I’ve used for text entry and editing. I know the article was focused on editing and not necessarily text entry but it really got me thinking. By doubling up and having two characters per key, it would open up a big chunk of real estate for things like cursor keys and other shortcuts.

I love typing and using keyboards in general. I love using Ctrl and Shift with the arrows, end & home, all of it. I would love to love doing it on my phone too.
