Commodore also had the PC Colt series PC compatible systems cheaper than IBM and Compaq etc.
The Commodore name and reputation of selling C64s in toy stores made businesses not see the Amiga seriously.
There also was that Amax Mac emulator for the Amiga as it used the same CPU as the Mac.
But all people could see was the AV part not the other parts.
Computer stores blackballed Commodore products because the VIC20 and C64 sold in toy stores.
A 286 was not as powerful as a 68000 with the coprocessors.
68000 w/coprocessors "felt" on par with a low end 386... though clearly it still lacked in raw computational performance.
The Amiga ran games better than even a 486 thanks to coprocessors multitasking events.
And people were paying for the big heavy cases, expansion slots, full keyboards and etc. Amiga didn't look the part. (And neither did Apple until the Mac IIs came out.)
