Windows, Mac, and Linux and other Unix-like systems all have such a
system variable already, in their respective graphical desktop
software. There is absolutely no need, and hardly any purpose either, in
creating another setting - in fact it would only create further
confusion. The respective already-existing settings for each OS were
already mentioned earlier in this thread; all that's required for
ConTeXt is to read the system setting that already exists and use it. If
the user's default turns out to be not set, ConTeXt could do any
combination of [complain] [open the user's system preferences for
editing] [use its own default PDF software] [whatever else Hans et al
have up their collective sleeve]. This means ConTeXt needs a
small-but-cumbersome list of all the places to look where the user may
have set their preferred PDF viewer, but that's just the price of being
cross-platform.

Anyone working with PDF is running a graphical desktop, right? I can see
that people may prefer to work in terminal emulators as a matter of
comfort/utility/familiarity, but is there anyone using ConTeXt and (on
Linux or other Unix-like system) not running X11? (I think it's almost
perfectly safe to assume that no Windows ConTeXt users are running
straight DOS without a GUI...)
