?!! iOS 5 betas were ridiculously buggy. Even the stock apps wouldn't launch. But all iOS 6 betas were rock solid. I was running beta 2 on my (main) iPad untill last week and had no problems with first or third party apps.

The rest of the comment is valid and I quite agree with you, but this one was (according to my experience at least) so wrong that I couldn't resist :)
