My entry to UNIX was AIX,...after slugging it out with multiple upgrades for Customers moving from MFT, MVT to MVS on 360's and 3090's.
Mixed in some VM - 370's.
Business World has VERY DEFINITE requirements.
Windows is fine for most folks....till you connect to the INTERNET....then it is a new GAME.
Businesses can handle it.
The newer Linux distros ,...like Zorin,....have gone the extra mile and are friendlier to those who like the Windows style of GUI.
Got my Daughter and grandson set up with running it....no problem.
PDP 11-70 running DEC Ultrix circa 1976...
Initial boot load 3 on, 3 on, 3 on, first 2 on (7776) ;-)
Very happy with Ubuntu.
