Re: know Windows
"Schools, non-computer teachers and support providers "know" windows."
Which Windows do they know? 3.1? [95?] 98? [NT4? ME?] XP? [Vista?] Win7? Win 10?
Your claim is patently ridiculous. There's almost as much in common between two randomly chosen versions of Windows as there is in common between a random Windows version and a random Linux variant. Pick one of the various Linuxes targeted specifically at making Windows users comfortable and the "migration" job's a whole lot smaller.
Unless of course you are one of those unlucky members of the Microsoft-dependent community, watching your prospects decline as MS move ever closer to a MS-centric corporate-operated cloud.
