I have spent something like £13,000 ($20,000?) on apple products over the past maybe 7 years so I'm not an apple-basher for the sake of it. Simply ditching all my ios devices would be expensive - although ios7 prompted me to go buy an Android tablet to assess the viability.
iOS6 was capable of fulfilling my expectations and 7 should represent improvements in every respect but it most certainly doesn't. I mainly resent the fact that apple now consider owners to be beta testers and their exponentially increasing control-freakery prevents you downgrading if you're not happy. This is unacceptable behaviour and will ultimately drive rational consumers away.
On my iphone 4, I can have up to a 4 second lag with some functions that were virtually instantaneous before ios7. (no, restoring has no affect...). Clearly ios7 was released while still exhibiting beta performance levels, and after 4 updates there are still serious issues. How is that acceptable? If I were permitted to install ios6 on devices that are my own property I wouldn't be typing right now......
