I might start using Ubuntu pure again. I honestly never understood the switch to this interface on desktop. Microsoft tried it on Windows 8 and failed.
My point was that MS hasn't suffered massive failure despite this ludicrous attempt at promulgating a feet/elbows interface on devices with actual keyboards and mouses.
Yes, lots of people (especially relatively technically aware people that I know) have resisted the upgrade to MS Windows 8 / 10 -- but they're still running Microsoft Windows.
Compare and contrast the Canonical Unity experiment.
That said, i think perhaps Windows 8 is the first (or second if one consider the Phone 6.5 to 7 transition) time Microsoft had ignored the muscle memory aspect that had kept their products up top for so long.
