To defend the A600 a bit (the one I have came from CBM as a tester and then I had nobody to send it to!) it did have some virtues. First, unlike the A500, it was easy to install an internal hard drive which made it the most portable Amiga produced. I have a bag from England that was designed to carry the machine to a buddies to play games on the TV. It was an excelllent game machine at the time (ironic since that's how Amiga started life).
I used mine mainly for telecom as I moved to the Mac. The A600 made a great second Amiga but it would have been even better with AGA!
