Isn't this a case of the small app developers not iterating quickly enough? If you look at the side by side screen shots the Zynga graphics DO look significantly better than the original game. Isn't the lesson here that if you do somehow manage to make a hit game you better reinvest as much as you can as quickly as you can back into future versions of the game to keep it as fresh and good looking as possible? How many updates has angry birds made since their first release? They're always releasing new levels and updates. I'm not defending what Zynga does in any way, but success brings copycats and first to market does not guarantee dominance of that market by any means.
