IOS6 ruining iDevices?

so i updated to IOS6 and i see the youtube app is gone because google and apple are in a argument but i use the youtube app provided by google on the app store but since its not HD then it does not look good. Tell me how you think IOS6 could have been better and what you don't like about it

Please search the forums. This has already been discussed in several other threads. We don't need to start a new thread on the same subject. Thanks.
