the illusion is almost real, because sometimes i also run linux in vmware/docker/... and when i am not paying attention i forget easily which os i am on.
the unix subsystem for win is quite boring as you can't mix windows applications with linux ones, for example running visual studio build from bash.
powershell would be probably worth learning, if i'd have to, but i do not. it may be godsend to win sysadmins though, as classic cmd is a 40 year old joke.
