Is Google really on a deal diet?

Normally Google gobbles up companies — more than 30 deals since 2005, usually small, privately held companies priced from $20 million to $50 million. But it hasn’t announced an acquisition in six months and Google CEO Eric Schmidt says prices are still too high right now.

But with some $16 billion in cash and securities in its back pocket, experts say Schmidt may soon be making a call. With valuations so low, and Internet software competition so high, Google can’t afford to pass up new technologies and growth opportunities.
