If iOS 6 or the other version of iOS had 'just worked' then this forum would be a lot smaller.
And I remember quite well all the people who screamed about iOS 6 ruining their iPads, and how they wanted to go back to their beloved iOS 5. This time next year there will be a new round complaining about iOS 8.
My eternal hope is that each year it will be a mostly new group, because the previous bunch have learned that they're not early upgrade compatible. Nothing wrong with that. Matter of fact there's probably more wrong with us crazy people who jump on an upgrade knowing how difficult and/or impossible it will be to go backwards if we don't like it, or everything breaks because it (or the most important app in the world) was not ready.
And if anyone dares say "This would not have happened when Steve Jobs was in charge", I'm blocking them, their mother, and their little dog too.
