or PC BASIC, from a college friend, for a
pittance.

It's important to remember the history correctly. In 1981, Microsoft was a dominant supplier of microcomputer BASIC. IBM was already going to talk to them about that.

IBM also wanted CP/M, and Gates assured them he could deliver that, too. What he ended up doing was buying QDOS from Seattle Softworks (for a pittance, really), and then re-working it into PCDOS. The rest is history.

  Had nothing to do with the Osborne
Computer Inc. company.  They just happened to
be one of several companies; Heath, Osborne,
..... - who at that time ran under CP/M.  So
I'd call it the Gates effect.

The Osborne Effect came later. It happened when Osborne pre-announced a PC-compatible portable computer. Once they did that, all sales of their CP/M portable virtually stopped. The reduction in sales bankrupted the company before they could finish and ship their PC- compatible design.

Of course, the wikipedia entry indicates that perhaps the role of the pre-announcement was overstated: http://en.wikipedia.org/wiki/ Osborne_effect
