I really love emacs -- it's a work of brilliance.
In my case I would say that I use firefox webapps 50% and terminal in the other 50% (e.g. bash, vim, make, etc.). I almost never use any other application. So I think it's clear where this is all going -- moving the terminal like experience into the browser. Which ultimately is way more powerful in some sense (images, equations, fonts, look & feel, links to documentation/web), yet very incapable in some other sense so far: the notebook cell editor has to be improved and maybe some other things: I often like to execute simple python scripts, that for example compile webpages using jinja (or sphinx) or do some sympy calculation, etc. And keep them around. So this workflow maybe translates into being able to easily run worksheets I guess. I don't know if we should even try to translate the whole python development to the web, e.g. being able to create a module (worksheet?) and then import it from other modules (worksheets) or simple scripts (worksheets)?
