How about actually polishing the OS and making it viable before pushing out more beta operating systems onto mobile devices?
That might help them in their quest to "kill the iPhone" or "kill the iPad."
Yeah google seems to be all over the place on the OS front, and I think it means a lot of half-arsed operating systems instead of one with the potential to really change Apple in the mobile space.
How is someone going to challenge apple in the iPad space when nobody touches them in the phone space. By opening up this new front Apple has created a lot of trouble for its competitors who already trailed them.
They can't just do what apple essentially did which is take their top notch product and make it bigger. They would be taking a second rate product and make it bigger which guarantees it would still be second rate.
Which means they will have to spend substantially more money and time than apple trying to catch up.
Plus Google's primary business is selling advertising. That is what almost all their revenue comes from. Apple is a hardware company.
Unless google can figure out how to make all these OS'es come back and increase the bottom line of their core business it doesn't make a lot of sense for them.
Not to mention with them running around stepping on everyone else's toes now everyone else is looking at them dangerously and they will end up losing access to ad views because they will be replaced by Bing etc.
