Never mind, I could be bothered. Sorry the aspect ratio is all messed up. With exception of maybe the first page turn, the Aura is faster or as fast as the 650 basically every time.

Actually it seems to have slowed down a bit. I remember trying before and it would turn the page before the Sony even flashed but perhaps my fingers were not synchronous.
