Updating was painfully and took about 3 hours. I am looking forward to a direct update next time. It took so long becuase I had to download and install iTunes 10.x first, back up the iPad anew, download and install iOS 5, restore everything to the iPad and THEN wait for about 15 apps to update for iOS 5 compatibility. There was a worrying message indicating that there was no iPad backup on my PC and that I would loose all my apps and data during the upgrade. I knew that there was a backup so I went ahead anyway. Apart from the above, it went without a hitch. So far I like:- Folders for photos. A simple enough enhancement but welcome. The potential of iCloud, although I haven't really explored it yet. A global setting for AirPlay to ATV. I REALLY wish the mirroring was available on iPad 1. No doubt I will discover some more goodies over the next few weeks.
