The NeXT cube is what the G4 cube should have been...

That's a NeXT brochure page.
The cube was cool. A real hardware marvel.
12" cube - black - magnesium
Optical drive that was supposed to be the next best thing in mass storage.. The idea was that you could have your whole life on a OD disk, and be mobile. <sarcasm>You can see where that went.. </sarcasm>
Some of the design philosphy from NeXT hardware made it into the newer Power Macs. (think ADC) On early NeXT machines (monochrome ones) the monitor was where you plugged in the keyboard and mouse. It was connected to the computer with a long cable. Even after the color machines came out, and the introduction of the Soundbox (keyboard, mouse, headphones connected to a little speaker, which was connected to the monitor and computer via a 'Y' cable), the idea of the computer as just another peripheral was there.
Very cool stuff. It's a shame OmniWeb 3 doesn't handle soo many things. I would love to have kept using my NeXT..
