It Is Google's World | Manufacturing Business Technology:

"Samsung has done a good job of establishing its leadership in Android, as has HTC. LG and Sony Ericsson are hanging in there. When Samsung first announced its home-grown bada OS, I was skeptical, but now it looks even more like it might be a “good to have” strategy. While it’s not an OS you hear about much in the U.S., it has made some inroads, garnering more global sales in the second quarter than Microsoft’s OS by a hair, according to Gartner figures released last week.

Google is assuring everyone that it’s not going to give preferential treatment to Motorola, but that also runs a little counter to logic. If you own something, you want to make sure it has the latest and greatest updates at the earliest possible time, and I guess you can leave the onus on the manufacturer by saying it’s their deal to be ready for the update. But that only goes so far. There has to be some degree of collaboration or else it makes no sense, and it’s clear Google will be influencing how Motorola makes phones"
