Probably the worst Amiga of all was the A500+.
A500 were used by the majority of the market for games, so releasing something practically the SAME as it (the A500+) with incompatibilities to games (KS 2.0) was pretty crappy.
A600 was never intended to be released as the next best seller, but only as a slim-line update to the A500 line.
It was crippled of any serious upgrades, however small form factor, easy upgrade to 2MB chip / 4MB fast ram, built-in PCMCIA port, IDE port, and RF/Composite out ports were a step up from the A500, for sure. The only mistake about it was the fact that Commodore didn't include some sort of a kickstart switcher in order to provide 1.3 and 2.0 roms at the same time, as the included 2.0 roms took away compatibility with a lot of classic software. Since it was intended as a games machine, the A600 should have had a kickstart swithcer in it definitely!
The A600 was no different of an upgrade from A500, as PSOne was to the original Playstation. :-) Simply a cash cow to the already well established best seller, however A600 probably didn't succeed as well as PSOne.
