I loved the A500 first and foremost, although the A1200 is up there. The A1200's capabilities were great, especially if you ponied up for some fast RAM. I think in many ways though it was a lost opportunity due to Commodore's useless management.
The A500 was, for the time, amazing. The A1200 was, for the time, merely good.
Both gave me lots of good memories though.
