Have you tried Bash on Windows? Been using it lightly (still dual boot) but it's pretty good experience.
Promising for sure.
Unusual that the Windows RT-alike supports it, though, but perhaps that's because Windows 8 and Windows RT were mutually exclusive in their hardware support (x86 vs ARM), and this isn't.
If you stay with windows you get more of this kind of thing, if you jump ship then you never have to worry again.
It seems like the intent is to end up in a similar place to iOS, with the entire system "curated" end to end. Which is not a bad place to be for many (most?) users. The problem with iOS model is that there's no way to escape it for power users, but it looks like it's not the case here - you can run 10 S if you want iOS-like experience, or you can run 10 Pro otherwise.
Well, I didn't.
