But the thing that shocked me is that the back button in iTunes actually works now without having to completely reload the previous app page I was viewing! In previous versions of iTunes, every time I hit the back button, it would completely reload the previous page, now it seems like it caches the pages for App Store. It is so much quicker this way and with the general slowness of iTunes, I really did think this was "magical". Unfortunately, the laggy GUI of iTunes is still there.
