Wish it didn't require iOS 6. I don't upgrade my iPad after previous updates made it slow.
I had a bad experience with my iPhone 3G. I had to jailbreak it just to downgrade back to a usable phone. That whole process took several hours of time, which I really don't have these days.
There are definitely times where it DOES NOT END WELL even though the device technically supports the upgrade.
A better policy is to wait for reports and then upgrade after a few weeks if they're positive.
A better policy is to wait for the official releases rather than buying a UDID slot from a dodgy website.
The one thing Apple really got right was getting a large percentage of their users upgraded to their latest OS. Hope it goes as well for iOS7.
My iPad is reaching its retirement age anyway.
