Steve Jobs NeXT Cube - Unix Workstation from 1988
When Steve Jobs left Apple in 1985, he decided to create the best computer possible. The result is the NeXT Cube.Its technical features, its object oriented operating system and its graphical interface, even its black case were very far from the standards. And NeXTStep - the Unix based operating system - is always considered as a reference.
It was sold with a lot of great programs and a very powerful 400 dpi laser printer. Some technical features were a bit strange (grayscale display, no floppy drive, no hard disk), but were modified in the next generation with the NeXT Station and the NeXT Cube 040.
Unfortunately, this computer was too expensive and had little commercial success, few years later, it was abandoned, but the later successors of this computer are still in use in some places, as servers. The NeXT Cube was used by Tim Berners-Lee as the world's first web server, and was also the platform for the first web browser.
