Nice post! I got an A500 back in '87 and it really opened my eyes to the idea of using computers for creative purposes (Deluxe Paint, Digi-View, DSS8+, etc).
I remember the A600 being panned when it first came out, with Commodore defending it mostly as a cost-saving measure. In retrospect, the A600 was somewhat ahead of its time - if there were more devices available for PCMCIA at launch time, it could have been a worthy precursor to USB as an all-purpose interface. The A600 would have been a powerhouse.
