I've got to side with those who said New Tek and the Toaster were the best thing that happened. The Toaster provided the means to take the Amiga to professional settings that would have been impossible to crack otherwise. Apple became noted for desktop publishing, the Amiga for desktop video. Unfortunately the market wasn't large enough to sustain the sales needed to keep the company going.
The worst thing, CBM's marketing efforts which tended to confuse the public. You want a computer that's easy to use and CBM's marketing message that the next door kid was the only one smart enough to use it was, according to many, offputting!
