Nothin' beats having one's own funny custom emacs hypertext note-taking code properly running again, though. Also, I have to say, having a lot more screen real-estate is really growing on me. I love how cheap it is to scan my eyes across things instead of page across them in fvwm2.
Weird Debian TeX thing of the day: I had to set my TEXINPUTS to
for some reason, rather than there just being a single point of loading for the system-wide tex stuff. Without the /usr/share path, it couldn't find article.cls, and without the /etc/texmf/ path, the color package was giving me bizarre (! Package color Error: No driver specified.) error messages because an important config file was unfindable.
