Steve would have been trying very hard to avoid the 'Osborne Effect', which was very well known to everyone in the early industry. Osborne portable/luggable computers had a very strong market share and growing, based on the CP/M operating system. They announced that they would be coming out with a DOS-compatible machine, far too early as it turned out. Everyone decided to wait for the introduction of the DOS machine, sales and revenue went to effectively zero, and the company died before it ever introduced the new machine.
