Anyone running it? Been running it on my iPad 4 since Beta 2 came out, and been very happy with it, very stable and frugal, but I am also loving the new font and little touches e.g. The buttons to go back to a previous app. How are you guys finding it? And what device are you using? If you want to try it rather try it on a spare iOS device and not your daily driver as I have read of some horrific experiences on iPhone 5 and 5S especially.
