I have the 2nd but since there will be no new apple tv this year i am considering getting the 3rd. Is it worth the upgrade ? i don't care about the jailbreaking . I notice that the 2nd gen seems to lag a bit with large picture galleries and will even just stop working and even basic things is sometimes slow. plus i have a 50 inch 1080p tv and the 2nd gen is only 720. I know netlfix has super HD, does that make a difference in PQ?
