The issue holding most serious projects back is MSVC's historic lack of support for C++11 (and now 14/17) features. Thankfully, it looks like this is starting to change with MSVC 15 [0].

As an anecdote, the (very large) project I work on at $DAYJOB is finally moving from C++03 to C++11 in the next few weeks.

There are more platforms out there than Mac OS X, GNU/Linux and Windows.

Many embedded platforms for example.

There are also enterprise customers that only allow for projects using the installed compilers, usually from the OS vendors.

May I ask you where do you work?
