I have an iPad 2 (original) and will probably keep it at iOS6 because iOS7 doesn't look great on my 1024x768 display. Text isn't crisp like it is on iOS6 due to the iOS7 font being thinner, and not optimised with lower-res displays in mind. I also don't like that they removed the blur effect after beta 4. Looks poop without it, sexy with it.
