The problem, as I see it, is that only Apple, and probably Google has a strategy that goes beyond "Apple is making money on these things, and we want in on that!".
The handset makers are just slapping phone designs together and seems to be putting whatever Android version they happen to have lying around on an USB-stick on top of them, and would much rather you bought a new handset than upgraded your old. That the devices are sold via the network operators who have their own agendas doesn't exactly improve the situation.
I do wish Google can strong-arm the Android status quo into order, but at this point I still feel about Android as I did when the handset producers first put out their own god awful touch mobiles to be able to say that "they had touch too". It's a sorry mess, hamstrung by the lack of coherent vision beyond greed, and lack of innovation.
I don't mind cheap copy-catting really, as it makes new technology available to more people and speeds up transitions, but from an innovation and integration point of view, well, Apple is where its at, and the ones who do little or no R&D and just slap Android on top of their devices don't really do their job cost-cutting. Cheap hardware, with lackadaisical support at similar or higher prices (as in tablets, phones are different price wise) does little to expand the market. I hope it changes in the future.
Interestingly, both Apple and Google are progressively moving beyond/side-stepping the PC, so regardless of how their market share war plays out, in the end Microsoft and Intel/AMD are the dinosaurs of this evolutionary path. They have little to nothing to bring to this table, and their business models won't work in this space. They both however have oodles of cash from their respective nigh-on monopolies to throw at whatever seems promising, and it will be interesting to see how they respectively will try to buy their way into mobile. But bring some true innovation and new value into the equation? Based on past performances, I just don't see it.
