People keep explaining this point to you, but you don't seem to get it; short of getting another device, it is impossible to "just try it out for a few days." One can stick with ios 6 or make the irrevocable decision to upgrade, but those are the only two options. I would have already tried it out otherwise.
Anyway, I will try it out when I get my next Ipad.
I say that because that is the direction Apple is going in and you can't stay on 6 forever. Lemme repeat that, you cannot stay on iOS 6 forever. You'll eventually have to get a new device and you're going to have to use whatever OS that device ships with.
It's just a fact.
Even if you switch to a different phone company, you're still going to have to use something other than iOS 6. In my opinion, the other phone OSes aren't up to the quality that Apple's OSes are.
