Mobile operating systems: Where the manufacturers play

If you were a bit shocked by Monday's news that Google was shelling out a cool $12.5 billion for Motorola Mobility, we don't blame you in the least. Indeed, the acquisition was unexpected considering Google has spend its life building anything other than hardware. The changes for consumers, Android's Nexus line, the supply of mobile patents, and the smartphone market as a whole will be momentous. What's more, it effectively means the end of a somewhat struggling company that not only was an early supporter of Android, but also did much to build the cell phone as we know it.

As the below chart demonstrates, Google is now a different kind of player in the mobile space. First off, the deal also leaves Microsoft as the only major smartphone OS developer not to build its own hardware. Sure, its partnership with Nokia is significant, but Nokia still stands alone as a separate entity (and as of now, we don't lend much credence to speculation that Microsoft might acquire Nokia). Secondly, Google also assumes a unique role of building hardware for its OS while letting other manufacturers use it through open source. How that will affect Google's partnerships and Android's rise will be fascinating to watch (Maggie Reardon and Roger Cheng explored the various issues on Monday).

For now, though, we'll have to see how it all plays out if the deal is successful. Google has made a bold move, to be sure, and by acquiring a host of patents it's entering new territory as a company. But, hey, that's never stopped it before.
