iOS7 is now three months old and after using it since the first beta, I have following comments to make: * I like the new design (most of the times). Maybe a little bit more contrast would be better, but I think this will come at some point * I love most of the new features * AirDrop is sth I am not using at all. It is totally useless to me because it works only with iOS devices, no OS X... * Stability: This is a big issue for me. My iPhone 5S crashes very often, especially in low memory situations or/and using multitasking. The situation has gotten a bit better, but it's just unacceptable for a premium OS to crash so often! Apple has to solve the stability issues ASAP. * iPad version: It is not optimized for the iPad. The animations stutter, Safari crashes very often and the OS also crashes very often. Apple has to improve here. iOS 7.1 is supposedly going to solve these issues.. I have to say, this is the worst iOS update ever, stability wise. It offers great features, has a refreshing new design but the stability is just not there. I wish the OS were more polished!!! Apple please fix it ASAP.
