Personally, I already updated my many iOS devices as well as a few demos. I far prefer iOS 7 to its predecessor. There are so many ‘under the hood’ features that make it well worthwhile. I especially enjoy the multitask switching and control center. IMHO, iOS 7 is fresh, clean, new and oh, so powerful. I can’t wait to get my hands on the 5s with 64-bit processing!
If you haven’t upgraded yet, or want to see the before and after, click and take a look!
