A Woz without Jobs would be a homebrew computing fan that would never have made any real money, but probably contributed a lot to the computing world through open source means.
I'd love to see "what if Woz hadn't met Jobs" and see what the world would be like - what Woz would have accomplished through his view of computing being open and free.
From reading his bio, I'm pretty sure he would have stayed at HP. That's what he really wanted to do. He might have contributed to many HP projects, but he would have just been another cog in the machine. His computer would maybe have found a place in folklore, but there would not have been an Apple ][, and certainly no Mac.
There still would have been Commodore PET, Vic 20, 64, Sinclair, CPC, MS-DOS, Linux. Xerox Star would still have existed. There might not have been Amiga. Maybe not Windows.
A more interesting question might be this: what would Steve Jobs have done without Wozniak?
