Seriously folks, Apple wouldn't be pushing the product if it wasn't good. If it was Retina display but couldn't support decent framerates for apps, they wouldn't have released it. Simply far too much money at stake to botch something so simple.
(And unlike most of the competitors, they aren't so desperate to keep their name in the press that they'll release anything they can just so they won't be forgotten...)
