Ron Johnson, Apple's senior VP of retail, exercised options for 700,000 shares of AAPL at a strike price of $23.72 yesterday. He sold later in the day at around $185. That's a net of over $112 million. Not a bad payday, but he certainly earned it. Johnson has led Apple's retail strategy from day one — and the former Target executive is arguably more responsible for Apple's retail success than Steve Jobs.
