I actually worked with or owned two NeXT computers. The first was the original cube that came out in the late 80's. It was owned by my university and was being used in the physics department to run simulations.
That thing was like science fiction. No computer out at the time could hold a candle to it, and the CD drive, though slow, held so much information that it seemed seemingly inexhaustible. The monitor was so big that it felt like my neck would wear out having to move my head back and forth to see the whole thing. (It was about 16.5" diagonal - ha!)
Several years later I purchased a nextstation turbo. It took everything magical about the original cube and just made it faster. At the time I also spent $1400 to buy an additional 450MB hard drive (note the "M"... not a "G").
I loved those machines.
An additional funny story. At that time I was also friends with some Apple engineers. When I told them that I had purchased a NeXT station they were both envious and dismissive.
Envious because they knew (and admitted) that this machine was years ahead of anything else on the market. Dismissive because the writing was already on the wall for NeXT. When I said I hoped NeXT would survive, they said not to worry. The tech was so good that it wouldn't disappear. Just the name. Somebody would purchase it and it would live on.
How right they were.
As an aside, with regard to Woz, he has done amazing things with his life. Things that Jobs never even came close to achieving. But these things all involved directly connecting with people who needed him as a teacher or philanthropist, and not so much things that would turn into money. Jobs accomplished a lot, but from (nearly) first hand knowledge, he was an ******* disinterested in helping anyone who wasn't already successful.* He may have built the world's most successful company, but Woz is the person I'd rather have an army of.
