Until you have to compile something major...

Then both OSX and Windows are awful.

I have yet to find an OS, including a wide range of the *nixes, where 'compile something major' doesn't fill me with dread.

[sentenza]

But compiling something major are just the baby steps. What if you have to run something over a distributed cluster? Or if it relies on dozens of libraries that were written for *nixes, without consideration for the quirks of Apple? What if you want to run part of your stuff "facing the outside world"? What if your machine (and code) must run for weeks?

I've only ever administered scientific clusters in linux, but from what I've heared from people that work as admins in "we use Apple" groups (and scarce they are), it must be absolute hell.
