Even if that were true, I give money to Apple and I don't give any money to facebook. Apple extracts thousands of dollars directly from my wallet, while facebook just sells my wandering eyeballs.
This thought occured to me the other day as I wondered in the Apple store to just look and walked out with my wallet $1500 lighter. In less than 45 minutes Apple extracted more money from me than Facebook ever did during the five years I used that site. Despite eyeballs, large numbers of users, and other assorted impressive metrics, there's still something to be said for functional (physical) products that solve problems and a solid product line.
