The Next Web has a fascinating link to a video documentary about Steve Jobs's time at NeXT that gives you some further insight into how he worked, and his determined and sometime volatile personality.
The NeXT episode was filmed by John Nathan for a TV series called Entrepreneurs produced by WETA in Washington D.C.
Some of the most interesting sections are Jobs pressing Joanna Hoffman at the 11 minute mark. Hoffman was one of the original members of the Mac team. His interaction with staff about delays in shipping at 15:33 is also a peek into the Steve Jobs worldview. You can watch the video clip below.
Jobs introduced the NeXT computer in 1988 after he left Apple. In 1996 Apple bought NeXT, Jobs returned to Apple, and the rest, as they say, is history.
