Agreed on the A600, I remember seeing one back in 1992 and thinking "Huh?". It was a step back from the A500, yet was priced at an extra £100, despite it's obvious place as a junior Amiga.
Another Commodore "Doh!" moment.
Next up is the CDTV. It was an opportunity wasted, thanks to it's relatively high price (an extra £250 IIRC over the A500) for a CD ROM drive, no keyboard and that awful CD carrier thingy that you had to eject, fit a disc into and then replace in the CDROM drive.
Personal favs are the A500 (it introduced me to the Amiga, along with however many million others), the A1200 (so expandable for a twelve year old design, you don't see Macs or PCs of that vintage with similar longevity do you?) and the A3000 because whoever designed it thought of everything...
