Personally I love my Northgate Omnikey, some love their inherited IBM keyboards. Whatever. Since you bring up Docker, it's the ease of use and sharability that are the big wins outside of how it's implemented. Heck, if you want to get real, it's a wrapper around lxc. Folks I know that are serious Windows hackers with zillions in funding decide not to compete with Docker because it wouldn't be differentiated or better enough to bother... They're on track for acquisition and it wouldn't have been worth lost momentum. People need new things to love as they fall out of love with the last that didn't fulfill an inner existential emptiness. (Chronic retail addiction.) Also people love to tear down the works of other people, because either they didn't think of it, they wish to justify their own laziness or are afraid of being abandoned.
