bash might be there, but the terminal emulation is still pretty bad. (I'm a week or two behind on preview builds, but I still couldn't run a bunch of ncurses/tmux/mosh type apps).
conhost.exe is a shame and it's kind of indicative how much joy it was just to get some basics (like QuickEdit by default, etc).
For windows, conemu ( http://conemu.github.io ) is a bit more annoying to configure than terminal.app, but works just as well, and even has the more powerful built in features like tmux. Of course you have to run something like msys2 (or maybe the bash for windows, but I haven't tried it yet) to get the "unix" environment.
