Hi: I have an iPad 2 with iOS 5.01 (just 2 months old). I am pretty happy so far with its performance, and have never experienced any battery problems. Now iOS 5.1 is available and, as far as i can see (and correct me if i am wrong), it does not seem to offer great advantages over 5.01. On the other hand, i am under the impression that iOS 5.1 was designed with the new iPad in mind, that we know has better hardware (more RAM, better processor). So, my fear is to upgrade just to find out that performance worsens. And, as far as i know (i am new to the Apple world), downgrade to a previous Operating System release is not easy to accomplish. So, is there any advice you can give me on this subject? What is the general consenssus so far? Is it convenient for iPad 2 users to update to iOS 5.1? Thanks.
