> Because it's really convenient to be able to make a note on your phone or tablet, then access it and make additional post-meeting notes shortly thereafter, on a laptop, all in the same interface (so you have the same features, or at least a set of common features).
That's why I personally want emacs on my phone and tablet. I don't know yet the best way to expose its functionality with a touch interface, but it's still, hands-down the best way to edit information.
Maybe something where a tap in the minibar offers some sort of helm- or ido-like command-picking mode, and with taps on the side to enable quick execution of text-editing commands? I dunno, really.

Emacs can handle formatting, tables and pictures if you want.
