One important question to ask though, is why are you doing this? In
general its better to ask Emacs for its capabilities rather than its
platform. 

Checking between console and windowing environment seems a good way to
do things. 

This way if Emacs on different systems gains new functionality, it
should all just work. 
 
Of course there are times when you might just not be bothered to do
this, or when its too much effort (checking whether external programs
like diff are available for instance).
