What does acme do to help on touch screens? I while ago I toyed around creating a vim keyboard for android, instead of having a virtual keyboard popup it show commands/motions instead. I abandoned the idea, but if text edition on a touch screen ever becomes feasible then I think the virtual keyboard has to go.
Unlike emacs or vim, acme leverages the mouse/gui for powerful editing - and I believe (multi)touch screens have the potential to be better guis than than screen+mouse. For one thing mice generally utilise at most three fingers and one hand - and IMNHO while eg blender/photoshop combine mouse and keyboard - the combination is awkward and not very intuitive.
I think (but am far from certain) that acme is a more promising approach.
