Fanboy Alert!
And hater conflator alert. The Newton was a product under Sculley and was among the first projects killed upon Jobs' return to Apple.
He was right about heading towards a quieter running system and based on those failures we have successful products of evolution. Anyone else is happy to keep making the same crap over and over again.
I wonder how many A4000D's are still operational. We experienced 100% failure rate from poor thermal design at DD and that was from a more conventional design and layout. It wouldn't take much to point out engineering foibles in almost every post-2000 Amiga desktop system, if one were so inclined, before getting to the let downs in the later chips. A500s unseated chips. A3000s were thermally better but an awful design from a maintenance standpoint, though nothing compared to what you'd get from Dell in the '90s, or pretty much any compact mini-tower PC.
It's either ignorant or disingenuous to poo-poo the LISA and Jobs while enjoying this website, any website, while enjoying an Amiga, a GUI, MorphOS, movies with visual effects, CG animated features, smart phones in America...
I could go on.
