For a second machine (maybe a cheap laptop) then yes, I would consider it.
As a side note, Windows NT had a POSIX layer as one of its three main APIs (Along with Win32 and OS/2), so in theory, at least, it should have been easy to port true UNIX apps to it. I have no idea what state the POSIX layer is in now; probably in a similar state to the OS/2 layer.
The POSIX subsystem was removed some time around Server 2003. They replaced it with Unix Services for Windows, which was based on an acquired technology, but that's no longer available as of Windows 10. After laying fallow for so long, I really doubt they used the old multi-subsystem architecture to implement this new stuff. Could be wrong, though.
