It’s here and the most noticeable affect is the instant aging of any apps that have not been updated.
On the whole I’m very happy with the update, though I have only had it for a few hours. I have two complaints worth noting.
1. I find myself accidentally activating Spotlight search a fair bit. This may be the result of lazy swiping on my part.
2. Folders are designed to take on the background color which almost causes them to blend into the background (especially on the iPad.) While not a functional issue, it’s an aesthetic I’ll just have to get used to in iOS 7.
So far I haven’t experienced any issue with the update on my iPhone 5 or my iPad 4. This looks like another win for Apple.
