For people who are having a hard time with iOS 7 lag, go to settings-> general-> accessibility-> reduce motion-> and turn it on. It fixed the lag.
Edit: I need to go back to being on topic. Goddamn my blasted my mind. So anyways, I love iOS7. The theme is perfect for me since I am asian. DAT COLORS.
Also iOS 7 has helped me dave a lot of time. I don't need to go open my iPad again to make small changes. And also the ability to take pictures while in the lock screen helped me. Thanks also for the control center for making those possible. Also as for the new camera filters I don't need to download any other editing apps. I also loved the new and easy-to-use multitask. Also love the new live wallpapers even though it drains battery (Actually it did not make any changes in my battery life). Also love the wish list feature in the app store. I also like the translucency of iOS 7.
Now these are what I hate:
The lose of the share widget. I mean I use to post every time on facebook!
The lag. Although I managed to fix it with a setting in my iPad.
No change in maps.
Although I still love iOS 7. Really, its just fascinating. Now I have more ways to beat my friends in a debate about which is the better smartphone. iDevices or Android
