Experience of iOS 7 on iPad 2?

Hey Core, Anyone have the beta of iOS7 installed on an iPad 2. I've just been reading another poster's account of poor performance on an iPad 3, and it gives me pause now at the idea of upgrading my perfectly functional (if slightly slow) iPad 2 to "Apple's latest and greatest". My hope is that such issues are confined to the first retina model, and that my lower resolution version will be OK. Anyone know?
