Oooh yes, I love Docker. Right now, I do most of my dev work outside Docker (because I don't want to rebuild the image every time I change a file..unless there's a way?). I do use Docker at intervals to make sure everything still works.
The shell being closer to production was more for familiarity sake. For me, I used to think I was going to be Mac for a long time because "Mac has a bash shell." Windows has a bash shell. In practice, I mostly use the ssh command! :)
Oh and the console window in Windows is now resizable! That drove me crazy.
