Google's purchase of AdMob now looks like a great exit by AdMob and horrible purchase by Google
It's a bit of a stretch to say that AdMob was a "horrible" purchase, though. They had to do something to move into the space. The only question is whether the iPhone is dominant enough in the market to make Apple's strategy successful over the long term -- if Android takes over the mobile market, Apple will only have a monopoly on a niche ad network.
All I can say is LOL! sorry.
edit: forgot to say it's a quote I saw on arstechnica live coverage.
