Well, i was in there from the beginning so believe me on this:
1. The price, too high for all models (the first a2000/a3000
and later a4000 i saw was in a tv broatcast studio)!
2. The a500 was great for gaming but BIG mistake making all the
games with ONE firebutton like the C=64 had (later/too late
corrected with cd32)
3. Sound chip should be 16bit in first place.
The only stuff that keeped me long time (until 1993/95) into the
amiga was the demo scene and games until they lost support from
companys b/c of high piracy just like the c=64...
