re: Angry Birds Shouldn't Seal Your Smartphone Choice
Ah, you're missing the point, even though you had it in your article. If the most popular mobile game ever isn't doing well enough on WP7 for the maker to be seriously looking to put their new version on it, then as has been stated, tther developers may think the same thing, and stay away.
As for quality apps, I've seen the WP7 apps several times as being described as generally of poor quality, with just a few gems. That's not a good sign.
But then, why should developers rush to this platform? It's not selling in credible numbers yet. Until, and even if it does, it will be far more profitable to develop for iOS, and even Android. Why waste their time on RIM and WP7?
