See my above reply for details to sibling comment, but basically, dumping a package manager on a running OS isn't the same as having a package manager to properly track installed apps.
This apt-get will only track stuff installed via it, while there's dozens of other stuff that just made it in sideways.
Also, ¿Can I run X, i3wm, etc? ¿Can I get rid of the entire Windows DE?
My point is, I don't use bash, because I want all the above. I've no complaint if you prefer windows, that's your choice. But don't tell Linux users that windows is now the same just because you have bash.
A better OS stack, where devs are busy moving beyond C, has better asynchronous IO stack, kernel level thread pools, embraces a mixed architecture with separated kernel and personalities, driver crashes don't bring the OS down, embraced by the games and graphics communities, allows for multi-GPU usage ....
Hardware support + you can run the Adobe suites, Microsoft Office, etc.?
I think WSL will be very successful among developers. You can just get any laptop from the store that runs Windows 10 and have Linux running at native speed (except I/O, which is currently a bottleneck in WSL) at the same time without the hardware compatibility problems, etc.
