Yea, noticed the same exact thing. At first I thought it was lagging and the device was acting slower but then I noticed that it's just the animations that are longer than usual...no lags, just long animations :/
It's pretty dumb in my opinion. You throw out the fastest hardware you've ever designed and slow it down with incredibly long animations. Plain stupid.
Nexus 4 up and running. Lovely. I am 100% android now. IOS 7 terrible looking on the ipad. No going back. A shame streaming quality on Sky Go and Netflix is poor on the Nexus 7. Hopefully only an update in the way.
Anybody and everybody on Androod needs to install FWeather widget. Simple text based weather with a twist. For eg mine currently says "Just Fucking Grey. Cold like a fucking fridge". Disable your GPS and it will say "dafuq dude. I don't have a fucking crystal ball here". Hilarious
