Usually technology dates very quickly but though twenty-five years old, the NeXT
computer and its operating system have aged well. In fact, the GUI looks very similar to modern desktops. In particular, the dock on the right hand side looks very familiar and this is not a coincidence. When Steve Jobs left Apple and set-up NeXT, he took a few key employees with him, one of whom was Susan Kare
, who designed the Apple Macintosh GUI. When Apple bought NeXT, one of the key assets they bought was the NeXTStep O/S, which formed the basis of Mac OS X.
