Thanks for taking the time and effort on a great point of view review.
IMO your entire review and conclusion was very good.
My one suggestion is for AmigaKit...
Set up and sell the sam460 in a true kit form. Include everything needed to be compatible and easy, but no case. It would save on shipping.
A complete kit would keep the "it's not compatible" problems out. And upgraded cards could be an option for those with more cash.
Make sure that items that can be "amiga" branded are branded. (extra points)
