I'm using an Air and iPad 4 side-by-side (both running 7.0.3) and I'm seeing the exact same issues on both devices: 1. Stuttering on home screen when using gesture controls. 2. Wallpaper selection screen stutters/lags when scrolling through wallpaper options. 3. Still takes an oddly long time to set wallpaper. With the x2 CPU upgrade and improved GPU benchmarks, I really expected a much smoother experience. In all honesty, I see no difference in the UI fluidity. The weight, form, etc. are all quite good but I'm disappointed with the A7 (or maybe iOS7...not sure).
