I am reminded of so many great and formerly dominant tech giants that have pursued a similar course of deep investment, acquisition, and R&D in newer and more cutting edge technologies outside of, or tangential to their main engines of revenue and dominance without ever fully moving beyond those engines. Thinking specifically of companies like Intel, Microsoft, Cisco, et al. All spent (and continue to spend) literal billions on acquisitions and R&D and yet all still pretty much make their money from their original core competence. I think Google's case is simply more ambitious. Android is probably their second biggest adoption success after search/web apps but it seems evident they're not satisfied with the financial ROI of it... It's a defensive thing. tl;dr: Pivoting is very hard and history is full of brilliant companies that have tried and never been fully able to.
