I didn't get an Amiga because of brand loyalty.
Back in the early 80's, my mother was a teacher, and, as such, she was invited to the major technical college in South Australia at the time (the Levels) to see a revolutionary new computer, the Lisa.
While she was there, she was told about an even more revolutionary computer called the Lorraine, and she told me about it when she got home.
Shortly after that I got my first computer - a C64.
I got an Amiag when I got the opportunity - a secondhand Amiga 500 with 3 meg of RAM and a 20 Meg hard drive. I didn't get it because it was a Commodore.
I got it because it was a Lorraine, or, at least, a descendant of the Lorraine.
Lorraine, of course, was the original name of the Amiga 1000, long before Commodore got hold of it.
Had Atari succeeded in their attempt to get the IP of the Amiga rather than Commodore, I'd have bought an Atari Amiga. Brand loyalty doesn't count for much in my book.
Interestingly, before they went broke, Commodore were intending to drop Amiga OS and produce a PC that ran M$ Windows NT. I wouldn't have bought one of those.
