Out of curiosity, are there any companies in previous history that model the approach Google has done thus far, such as expanding into a vast amount of industries and successfully becoming a contender in those? Anyway, I'm sure Google has enough money to support any failures (this point was made in a previous article about the multi-tool card). But, in the long run, how will Google prevent itself from appearing to look like a monopoly (such as Apple's iPhones in the earlier days)?
