More and more app updates are requiring iOS 7. My iPad 3 is jailbroken and on iOS 6.x. It works well except for Safari's poor performance and frequent timeouts. I'm thinking of upgrading it to iOS 7 and jailbreaking it, but I'm concerned about what I'll lose if I upgrade? Judging by the many complaints, iOS 7 is slower and stutters a lot on the iPad 3. The other thing I'm worried about is AirPlay reliability. AirPlay performance has been amazing on iOS 6; I almost never have problems with it. In contrast, AirPlay reliability on iOS 7 (on an iPhone 4 and 4S) has been abysmal. Trying to AirPlay to my Apple TV or XBMC or Plex rarely works, with less than 50% of AirPlay attempts succeeding. So, is it worth upgrading my iPad 3 to iOS 7?
