The logical progression from Vic-20 to C64 to C128 to A500. Just seemed to be "right" to me. The Amiga was doing so much more than PCs at the time were (again, so it seemed to me).
I remember seeing PCs at Costco with their brand new "VGA" displays and thinking "Oh man, that looks so good!" and then wondering why my A500's display was in glaucoma-vision (it was a shitty color TV - didn't get a monitor for my Amiga for a few years

)
Brand loyalty kept me with C= up to the fall; I'd have stuck with it even longer but for having a sit down talk with a guy who was doing work for MS, and another fellow working with NextStep. Those first steps away from DOS on the PC were shaky, hesitant ones but I could see where the future was headed.
Now I just fondly remember the good times.
