What is all the fuss about a second analog on a handheld? Why is it so important?

A horrible control scheme, there is no precise aiming at all using the XYBA buttons to aim.  It is barely usable in Mercs 3D which has a slow pace, for any modern FPS it would not work.

I dunno. He's using the default controls and I think the FPS controls settimgs are actually better. Not too shabby, eh?  Of course a second analog nub would be better but the touchscreen and the d-pad take up a lot of the slack (weapon swapping, melee, 180 turning, grenades, etc).  To each his own, I guess.
