Typically I have three windows open: Emacs and rxvt on tag 1, and Firefox on tag 2. Emacs runs in less RAM than Firefox or what many of you use for playing music, and it does all of the following:
Emacs: editor, chat (rcirc + bitlbee, comint), email (gnus),
rss (gnus), address book (bbdb), shell (eshell),
calendar (calendar), calculator (calc),
music (eshell + ogg123), IDE,
remote machine access (tramp)
I am astounded by how many respondents regularly use file managers!
