I was a Windows user for years, since the 90's; so it has been a learning experience on this Apple format; but learning.  However it was really fast at first, but now runs at about half the speed it did, maybe.I am retired, at age 80; but spent many, many years as a Master Photographer, Master Artist, etc., even teaching pros in 7 states.  Plus, back in the 50's and early 60's I was a printer; so have had a lot of experience.  Some things I like, some I do not.  However I have only had this unit for less than 6 months now, so HOPE it will grow on me and get better as time goes on.
