Yes it was very nice of Rovio to not place the paid version on the market that made them well over $12 million. And instead to force people to install a new app for a new market that requires a new payment setup and can't seamlessly install or maintain apps. I am so proud of Rovio for stabbing all of their early supporters in the back like this.
+ 1 , if the app is free then why do they need my credit card # . I never had to enter my info into the Andriod Market until I was ready to start paying for apps.....I think I'll stick with the Andriod Market !
