A little late, but I admit it, I'm an app of the day person. Why? Most apps are already in the market, and as before, why buy an app with DRM when I don't have too? Case in point, I got weatherbug elite from amazon. Works fine on my S7, crashes every few days on my vibrant and demands to be reinstalled. So now my vibrant just has the free weatherbug app. I suspect it's a problem authenticating itself. I know you have to have logged into amazon before the amazon apps work. That's 2 strikes. Come to think of it, amazon is blocked from 3g data (droidwall). I wonder if it occasionally re-authenticates apps when in use? The S7 can only update the weather on wifi, and amazon can re-authenticate via wifi. My vibrant can check weather on 3g, but can't re-authenticate via 3g = crash? Possible 3rd stike if amazon has to use 3g data (from a limited plan) to verify apps occasionally. All the more reason to buy them via market if available and useful.
