The NeXT systems didn't sell wel to end users. But they were a hit with developers. It was far too much, too soon. Stuff we are seeing today in OS X, but slightly modified came from NeXT.
When Jobs left Apple he took the style and clearly the genius engineers with him. I mean these systems were beautiful and powerful!! Take your pick!!! I am a wealth of NeXT info and pictures, so if anyone want to see more including the actual NeXT Cube brochure in PDF let me know. It's too big to attach.
When I make more deskspace I'll set up my NeXT Cube and snap a pic of it.
