Microsoft and Canonical partner to bring Ubuntu to Windows 10

Would anyone be able to give insight on why this would be useful? Im curious, sure, but I'm at a loss to think of a use case.

My guess for the marketing target is developers who use Macs because their tools of choice are native to POSIX, with Windows API implementations as second-class citizens at best.

Maybe things have improved since, but at least a few years ago, it was always a crapshoot to try to get some new open source tool set up on Windows/Visual Studio, vs. batting close to 1.000 on Mac with configure && make && make install.

Another way to put this is that the world Terminal.app gives you access to is a huge selling point for developers, and this is part of Microsoft's attempt to provide something as useful.
