The NeXT Computer (also called the NeXT Computer System) was a high-end workstation computer developed, manufactured and sold by Steve Jobs' company NeXT from 1988 until 1990. It ran the Unix-based NeXTSTEP operating system. The NeXT Computer was packaged in a 1-foot (305 mm) die-cast magnesium cube-shaped case, which led to the machine being informally referred to as "The Cube". It cost US$6500.
A NeXT Computer was used by Tim Berners-Lee at CERN to develop the world's first web server software, CERN HTTPd, and also used to write the first web browser, WorldWideWeb. This workstation became the world's first web server on the Internet.

It's surreal to find out that even with the Internet, Steve Jobs had an influence on it. Such a humble person not to brag about it.
He developed the NeXT, when he briefly left Apple. Even then he didn't give up on his vision. Upon his return to Apple, he proceeded to produce the iMac. From there, the rest is Apple history.
Oh, and iMac, iPhone, iPad, iPod... wanna know what that "i" means in front of the name of the Apple devices? Well, here's Steve telling you himself from his 1998 introduction of the iMac:
We will miss you Steve.
