The A2000: overpriced and underpowered. The flagship Amiga of its time should and could have been so much better.
I'll think of 2 more later 
The A2000 was certainly overpriced when it first came out, but this a common theme with new things: rake in money off of all the rich people who want the most powerful system. A year later it was $2000 with 020 and 50MB Hard drive. Compare that to Macs at the time they were about $3000-$5000.
I thought the A2000 was great, you could switch off the Accelerator and play all the arcade games. Switch it back on and do some more serious work.
