Fred, first things first - I cant believe you responded to this post - it was a pleasant surprise - Thanks !!
1. AAPL has gone up 7.4x since the day you sold.
2. "we would have invested millions in airbnb" thats the whole point, you could have invested millions in AAPL as well.
3. Your other investments are stunning. You are so right, some of them would blast past the 7.4x AAPL benchmark - hey thats a new term for vc - the AAPL benchmark!
