From a QA perspective, probably 10% of the effort is OS X, 40% for
Linux (mainly due to the sheer number of Linux distros), and 50% for
the various versions of Windows and different configurations.

From a development and support perspective, Linux & Mac probably
equate to 10% of the effort each. The rest is Windows. The reason it
tends to be so high, is the sheer number of different (and
unpredictable) possible configurations of things like local and domain
security policies, filesystem ACLs, effects of folder redirection,
UAC, changes to utilities between different releases (eg. cacls vs.
icacls), encoding and locale issues and oddities seen when running
over terminal services sessions.

Thanks Greg.
