If Apple's successive post-Jobs CEOs (Sculley and Amelio) hadn't maneuvered the behemoth into a blind alley, NeXT would indeed have faded eventually. But with full access to Apple's resources, the NeXT team were able to turn things around. Sitting on the top shelf in my office, gathering dust (I turn it on every couple of years) there's a cube. A nice shiny silver cube that runs something that looks eerily like NeXTStep, if you squint at it, with a classic MacOS emulation bag on the side. If that's not a statement by Steve Jobs (and a trophy of success, to have the elbow-room to make such a statement) I don't know what is!
