This is going to keep coming up, if we move the Data and Typeable classes out...

OSFlavour - dislike, flavour pretty much means "it tastes like".
Windows+Cygwin has flavours of both Windows and Unix. We want to say
this is the OS you are using, its not just "a bit like" this one, but
it really is, and it can only be one.

OSType - seems fine.

OSKind - again, has a slight "kind of like", and again Windows+Cygwin
is kind of like multiple things.

OSName - the name of your operating system - this is the one I would
have picked.

OS - nothing wrong with short names, especially when they are common
abbreviations

OperatingSystem - but no point optimising for character's when people
are doing something we don't want them to be doing :-)

I think in the end I'd pick OperatingSystem, as its very clear what it is.

Thanks
