You can always take a closer look by pressing a button, and drag out of 
the 'splash' if it's wrong.

Yes.. I'm most unhappy about esc and del, and I want to get PG Up and Pg 
Dn in there to.

The numbers are OK, The letters reuse knowledges that T9 users have. The 
  3 buttons at the right feels OK, as do the cursorcontrolls.

Is not this more the apps responsibility.... The messenger app know who 
I'm typing to, and can analyse what I usably type to that person.

Yes, hexagons is better then yes.. just harder to mock up ;-)

To short drag might make it hard to just tap the 'central' button. But 
the splash should come up centered round the actual press point, not the 
pressed buttons center. That way ju can just strike your key... a 
reasonable right strike starting in the reasonable right spot will work.

XHTML with embedded both javascript and embedded PHP with embedded 
SQL... Lots of strange chars... Then there's the editors. A lot of stuff 
use emacs key binding. Other 'windows' style (like press shift and move 
the cursor to mark)...

~90 should work. A lot of char may be changed when shift is pressed. And 
removing the 3 boxes frees 3 keys... but as the strokes still is slower 
than typing on a real keyboard, keeping the number of needed strokes 
down is good. so many keys is good.
