Some analysts still hope that ecosystem lock-in will let Apple lock in considerable dominance of a market that otherwise wants to explode into diversity.
Facebook still faces enormous additional supply coming into the market as post-IPO lock-up agreements covering well over 1 billion shares expire in the coming months.
But note that lock-in is inefficient (that is, it is a kind of market failure) only if the inferior product survives despite the fact that the benefits of switching would exceed the costs.
Facebook (NASDAQ:FB) has been one of the strongest stocks in the market over the past three weeks following the expiration of an 800 million share IPO lock-up period.
