Chrome, Android OS Will Not Merge, Google Chairman Says

Chrome and Android operating systems will remain separate products, although there could be more "commonality" between them, Executive Chairman Eric Schmidt said. 

Speculation about such convergence has been an obvious subject of speculation as tablets and phablets blur the lines between "phones" and "personal computers," raising the possibility that a common operating system could evolve out of the separate Android and Chrome environments.

It still is possible something like that might happen in the future, but the current thinking probably is that merging the two operating systems would result in a creation with too much overhead and "weight," making the resulting OS sub-optimal compared to distinct approaches optimized for the PC and smart phone-tablet environments.
