>text-based programs Not text based, it has buttons, widgets, can embed pictures and graphics. >reliable, and familiar programs to accomplish In emacs these bits of code are integrated, so I could, for example, save an IRC chat as buffer, edit it, and send a e-mail. Or open an interactive REPL of maxima, for example, copy result to latex having embedded previews for formulas, and then compile it to pdf (and preview in emacs). Different parts could be combined in any possible way with elisp code. You can easily call any email-related or rfeed-related function from your code at any time.
