You do not take his words seriously. Google has bigger plans for Motorola. Some of which we would see later this year. They need Motorola for a possible situation where Samsung forks Android away. Patents are a big part of the deal but I doubt Google thought that they would recover their investments through royalties. Loads of people said acquiring YouTube was a mistake. Just give it a year or two. Microsoft paid 7 billion dollars for Skype. Around the same for aQuantive which they now admit was a bad move! Google paid same for Motorola Mobility and I am sure it is worth much more (IP and assets).
