I retired last year but I too had to use a Mac for a year. It was the first and last time I ever used a Mac. I hated it. So many quirky behaviors, window controls on the wrong side, just wow I had a whole list I could have articulated last year but thankfully it's a distant memory now.

It isn't a problem as long one understands the difference between UNIX and GNU/Linux.

For me Linux had been mostly the UNIX that we have back at home, while most work was done in Solaris, HP-UX, Aix, DG/UX.

I am not attached to Linux specifically.

We're getting there. But I doubt your average joe will ever use anything that may require even once to type something on a terminal.
