It's a bit slow and clunky of my iPhone 4S. Apps like Twitter and Facebook are definitely taking longer to open. I've had one reboot as well when opening a particularly demanding app.
Interesting to take a look around. Not sure if I'll keep it or go back to iOS 6.
Yeah, agreed- a bit clunky on my 4S. Did yours get very hot too to begin with? Mine seems to have settled down, but I had to leave it powered off and off charge for 10 minutes to let it cool...
Also had a few odd moments where the screen has gone to minimum brightness, had to lock and unlock to get it back again.
Other than that, I quite like it. It probably won't stop me moving to Android though for my next mobile though, I was really hoping for some widget/live tile action in iOS, I use them a lot on Android.
