Google has left the hardware to the hardware makers, preferring to write the structure (the OS) and reaping a direct cut of the innovations to come (the APPS).
IF Apple had done what Google is doing, nearly EVERY phone in the world would be running Iphone OS. Every phone would be locked into buying apps from Apples APP store, and Apple would be able to sit back, lock the door (the market), while others scratched to get in.
Instead, you will end up with Apple and RIM with about 50% of the market, and Android with 50% of the market (baring some disruptive innovation).
I argue that this parallels Apple failure to successfully release its OS to third party computer builders in the 80's...which is why Apple has about 5% market share of desktop OS right now.
Google GIVES away android so that they can have handset marketshare, and thus a MUCH bigger cut of APP money than Apple will ever have.
We could just sit back and shoot these things at mars and pelt it with different plants to see if anything takes. I am guessing we would want to aim for the areas that border the north and south poles, or craters with shade that might have a chance to hold water for more than a few seconds so the plants could get a drink.
