When Jobs spoke to Playboy in 1983, Apple's biggest rival in producing PCs was IBM.
So he didn't seem off the mark when he said, "I don't think there are going to be a lot of third- and fourth-place companies, much less sixth- or seventh-place companies. Most of the new, innovative companies are focusing on the software. I think there will be lots of innovation in the areas of software but not in hardware."
Actually, it was software giant Microsoft who soon outran the pack, leading to such an iron grip on the market that the US government eventually investigated it for anti-competitive behaviour.
Today, the biggest software spoils are shared between three big names — Microsoft, Apple and Google — while the hardware battle is waged further afield with Samsung, Dell, HP, Acer, and others all in competition. This is one that Jobs got wrong.
