why? There will be an android app store, it's just going be policed by Amazon, more or less the same approach as Apple, considering that this device may well be heavily subsidized by Amazon i think they are allowed some say on what goes on the thing, if it works out who knows the price may come down further if Amazon can get better revenue streams from selling android apps
what Amazon can add to this equation that the others can't is the eco-system, Amazon can offer a complete eco-system that comes close to rivaling Apples, in fact they have a more diverse eco-system, id imagine if the sales of this device drives the sales of other commodities on Amazon then it can also help drive the cost of this device down too, factor in the fact that Amazons cloud service is an industry standard and you can see how Amazon might actually pull off what others have failed to do, compete against Apple's iPad
