Apple, as in the computer company, fought with Apple, as in the Beatles' record label, for decades over the name Apple, and just recently settled (that's why all of a sudden you can get The Beatles on iTunes).
And now the Velvet Underground is feuding with the Warhol foundation over their Banana logo, and whether it can be displayed on iPad covers.
I think there are two lessons here:
1. Don't get into a contract or contract dispute with Andy. Even a quarter century after his death, he'll still probably win. That guy was a business genius, and don't forget it.
2. Simple fruit as an identity may not be as simple as it seems. Sorry, Apple Martin.
