It is mostly for visual studio work.
At my school, we use visual studio in computer science.
But we are moving the school to chromiumos builds. (if we can get them booting)
We would also like the ability to still use visual studio, but there is no online version of it.
At the moment we have been going through hundreds of online IDEs but cannot find one as good as visual studio.
But now I think about it, Having a VM run on old hardware just to get visual studio would be a bad idea,
not only for speed but for maintaining policies (Disabling: cmd, PowerShell and C drive access).
