On my iPad mini retina, every single app crashes, keyboard shows up sideways, inability to swipe down to respond to messages, unable to search in App Store and the list goes on. Those were all things I was able to do on the previous beta. On my iPhone 5 the situation is not as dire but it's a noticeable step backward in usability. Beta 1 was quite stable despite being slightly buggy (on both iPhone 5 and iPad mini retina) but beta 2 is almost unusable in its current state. anyone else seeing the same thing?
