I think what really annoys me is the fact Apple do not allow their customers the freedom of choice to return to their previous iOS.
The option to return your iPad/phone to its previous state is even more important when there are radical changes from the previous firmware, but because Apple like it does not mean everyone does, they are the only company I know which does not offer democratic choice, IOW if you don't like it...then it's just too bad..you don't have a choice.
Imagine.. A customer bought himself a new iPad a month before the iOS 7 release, the customer is very pleased with their new iPad, he likes everything about it, his timeframe for returning it under Apples no quibble return has passed, but he his happy with it and intends to keep it.
Then Apple release a major update which changes the way his device worked or looked, his expensive iPad no longer functions as well, and he is no longer happy with his new purchase, but he cannot return it for a refund, and neither can he return his iPad to the state it was before the update.
Not having the option to return to the previous firmware is totally undemocratic almost to the point of dictatorship, because Apple have removed any choice, in fact I would think customers would have some legal validity if they chose to return the product to the store, as the product is now so different from the iPad they initially purchased.
Regardless of the product, we all know and accept the risks when we update firmware on electronic equipment, things can go wrong, and sometimes the update may have inherent issues, it happens quite often with new bios releases, but the user almost always has the option of returning to their previous operating system.
Why Apple insists on closing the option to return to the previous iOS after just 1 or 2 days is totally ridiculous, and is something they need to remedy. People need, and want to be able to decide themselves, so can Apple please STOP this stupid practice of preventing the return to a previous iOS version.
