One problem Apple computer had is that it's trademark was limited to computing. That caused problems when they branched out to other markets such as 'computers that can do MIDI'
In particular, they had quite a few disagreements with Apple Records about doing audio. Even though more or less the only people who know Apple Corps/Records think "of the Beatles' records", they took action against Apple even as early as 1978 (http://en.wikipedia.org/wiki/Apple_Corps_v_Apple_Computer)
I think those lawsuits may have affected company culture at Apple Computer, now Apple Inc.
