Over the years I have also gotten a few calls from someone, informing me that they want to do something to fix or upgrade my "Microsoft Computer". I politely inform them that my two Epsons, a QX-10 and a QX16 are working fine. They always hang up without a word.
Both computers have worked without a glitch, to my satisfaction since I bought them in 1981. I have one on each ranch and have never been sorry that I bought them. They do not have the "bells and whistles" of modern computers, but they do my work and I never have any problems with them. I am typing this on the QX16. Both permit me to do things that even modern Microsoft computers cannot do. Of course, there some things they cannot do, but I don't need those things.
Just for information, they were not cheap in 1981. I remember paying about $4,500 for the QX10 and about $5,200 for the QX16. Using today's inflated dollars, even those prices are probably less than I would have paid to own, upgrade and repair Microsoft software computers all those years.
