Mir is a desktop technology that pushes forward the linux desktop and ushers it into a new era. Mir is developed by Canonical, arguably the best Linux technology OS company in the world. Canonical develops Ubuntu, the best and most popular version of Linux. They are basically the Microsoft of Linux, dominating the field. If you haven't tried Ubuntu, you should, as it eclipses all other Linux distros that may have left a bad taste in your mouth due to them being to difficult to use. Canonical really likes to push technology forward as one of the most innovative companies in the world when it comes to operating systems and they have shown that outstanding vision combined with excellent execution is the way to go in the 21 century when it comes to IT. There really are only 3 companies that make operating systems: Microsoft, Apple and now Canonical. And Canonical is ascending fast to become a real pretender to the throne!
And where, in all of that, do you rank Google, developers of the Android and Chromium OS / Chrome OS operating systems?
