Post what apps you regret buying, and their price. I regret getting Real Racing HD (9.99) and Fieldrunners (6.99). Not that they're bad games, it's just that I didn't end up playing them as much as I thought. I also regret Quickoffice (got it at the intro price, which was 9.99 instead of the current 14.99) - just an all around horrible suite, feels very unpolished and barebones. How about you?
