Ubuntu on Windows

This is great to see, as it's very similar to the approach that we took with LX-branded zones on SmartOS[1][2]. I commented at some length on the other thread on this on HN[3], but I have a bunch of questions about apps that we know to be thorny: Go, strace, tcpdump, systemd, etc. As we learned, this approach is entirely possible -- but there are many, many details to be nailed before you get to the point that you can run production applications on it. So while the journey across the uncanny valley of Linux is long and arduous, we know from our experience that it can be done. Very much hoping that Microsoft gets to the other side -- and that they open source it all so we can all learn from one another!

Can windows 10

    apt-get install/run most/all the x/gtk base apps

    apt-get build from source those apps.

    ?

If so, I will consider switch.

No. No GUI applications (currently, and no announced future support... and I wouldn't bank on them doing it).

Fortunately X11 is "network transparent" and there's X11 servers for windows. It shouldn't actually be that hard to make this work (though the perf will probably be pretty bad in a naive implementation).

At very worst you could SSH to localhost and X11-forward to the same host -- but you can optimize that.

Nope, XMing works perfectly if you export the display to localhost (the default) and it's really fast, it even has GL support with MESA , with hardware acceleration.
