One thing that the Google / android folks will have to deal with will be the legal issues when they have to much of the market and to many vendors are selling android gear.

it just might turn out a lot like what MS went thru.

dumping a product at below the cost of creating it and getting so many OEM's to make it the default on the devices and so on .... not exactly what MS did but there are some common things in the mix that could spell trouble for them down the road.
