This is not a comment on the OP's question about iOS 7. I've not used it and have no idea if there are any bugs. But your comment about the iOS 6 maps brings up a larger issue that is worth addressing. It is a fact that being successful makes an individual, business, sports team, etc a target for others who take a sick delight in seeing success toppled. Apple and the iPhone are an easy target because they are wildly popular and the product continues to have amazing success. I believe this is a large reason behind the current "Apple didn't innovate anything" with iOS 7 and the iPhone 5s. A critic or tech blogger could say "the iPhone 5s will provide an outstanding experience for consumers because..,." But it is more popular to magnify perceived shortcomings or accuse Apple of not innovating.
You raise a valid point - and one that’s been discussed here in various threads... the bottom line is "haters be hatin'". No matter what the product, there are those who have to try to tear it down. I fully understand that there are many other options out there, and that any of Apple's products are not for everyone - whether were talking about phones, tables, computers, music players or tv-attached entertainment boxes. I’ve said all along that as a consumer, you do the research and go with what works for you and your situation.
With that said, however, all companies do things sometimes that don’t make sense to the general public. Apple was in a hurry to shed itself of the Google influence, and dropped maps before they were ready with their own replacement. Personally, the Apple Maps app worked very well for me. I never had any issues with it. I also realize that some did. But because there were issues for some people and in some areas, the Apple Maps app became a lightning rod for all of the Apple critics. Despite the wringing of hands and the gnashing of teeth, Apple survived that alleged fiasco well. The same thing happened with "Antenna-gate" with the iPhone 4 launch. Jobs was ridiculed for his "you're holding it wrong" response to the reported problems. In large part he was right. There are/were a number of other phones that exhibited the same behavior, but it was the new Apple device that was set up as the poster child for failure.
But historically Apple has taken features and functions that, admittedly, may be developed or introduced by others and tweak them and make them work - and they work seamlessly and often flawlessly.
When you’re successful - "Apple successful", you will always have a large target on your back. So far, Apple has responded well and not only survived, but excelled.
And the bloggers and "tech writers" find it fashionable to bash Apple, its products and its success. And they will continue to do so because it’s "good copy". Remember the newspaper adage: It’s not news when a dog bites a man. But when a man bites a dog, THAT's news.
