After some apprehension, I installed iOS7 on my iPad 3 too (I'd done my iPhone 4 already). Now that both devices are upgraded I have to say I like it just fine. I'm not sure why I was reluctant to 'change' but let's just chalk it up to being over 30.

Nothing is amiss and the new interface is really quite an improvement. My only beef is that up here in the land of short riding seasons and mukluks, we don't get iTunes radio.
