Well, many of us are forced to run it. Let's not forget that Apple loves forcing their customers upgrade to the new version by (probably unnecessarily) making their leisure apps (iPhoto, iMovie, Garage Band etc.) iOS6-only. They did this right after the iOS6 release. It's only the iWork package that remained iOS5-compliant.
I myself would have happily stayed on 5.1.1 for, if nothing else, Quasar compliance; nevertheless, "tricks" like the above (the above three apps' only supporting iOS6) forced me to upgrade immediately after evasion was released.
