Holy cow, I wrote a book!
Unless you've been living under a rock,
by now you know about MSDN's
low bandwidth view (aka ScriptFree)
But there are other views too, like
PDA view (for when you want to look up MSDN documentation on your phone?),
Robot view, printer-friendly view, unstyled HTML view...
(See that first link above for more details.)
But in addition to all the views, you can go directly to the back-end
that drives all the data:
MSDN/TechNet Publish System (MTPS) Content Service.
With that interface, you can request the back-end data and
format it any way you like.
an MSDN Magazine article which builds a documentation viewer,
the author of that article
a command-line tool which returns the content as a man page.
(Update: Looks like the command-line tool no longer exists.
Sorry, all you retro-heads out there.)
