Where is Linux
While watching an NFL game, I noticed a significant presence of Microsoft Surface tablets being used by coaches and players.
When I was in the hospital this past summer for an emergency, I noticed all of the workstations running Windows.
When I was at the dentist a few months ago for a routine check and cleaning, I noticed all of the workstations running Windows.
When I was at the auto mechanic I noticed his office computer running Windows.
While I understand the marketing avenues available that allow Windows to be so easily supported, I do not think Linux based systems would change my observations.
None of the vertical software being used in these observations is available in Linux land. Yet suppose that was not the case.
There are no true Linux based tablets (Android is a data mining operating system and long ago stopped being a free/libre based operating system).
More importantly, all of the users in my observations do not use the command line. They do not spend time tweaking the desktop or operating system. Their attitude is, simply, everything just works.
Which is not the case with Linux distros. The presumption with Linux is tweak, tweak, tweak.
