I had a chance to speak with a Google engineer about this not long ago. They said that Chrome was meant to be cloud-centric, whereas Android focuses more on Apps. (A bit of an oversimplification, but generally accurate.) My take: ChromeOS may actually be better for Google's interests in the long term. However Android's success has resulting in significantly more momentum currently. The release of Chrome on Android might be an effort to move Android more in line with Google's larger goals.
