Much as it pains me to say, as a die hard Mac fan, Apple's success really largely rides on other products. The iPod (which was not at all developer friendly) saved Apple commercially for several years. Yes, the Mac business had turned around a few years before, but e.g. the year before the iPod, Apple had the disastrous Power Mac G4 cube launch, which led to some unprofitable quarters. The iPod ensured that Apple's fortunes were no longer tied to new Macs (even though there were no G4 cube repeats). And the big influx of developers came with iPhone. Not sure that Unix was that important a selling argument in that segment — it's certainly there behind the scenes, but does not play much of a role in developing.
