There was a time when Sony was the undisputed King of the PDF experience on their entire line of electronic readers. During this era the majority of readers did not feature a touchscreen display to pinch and zoom, so we had to make due to advanced settings. Kobo has slowly been making inroads in usurping the crown away from Sony with their PDF rendering technology.
Today Good e-Reader compares the new Kobo Aura and the Sony PRS-T3 and looks comprehensively at the overall PDF experience. Both of these devices allow you to pinch and zoom, and they handle this in completely different ways. Kobo has moved into more of a tectonic gesture based control scheme, while Sony still puts a heavy emphasis on reflow and zooming.
The video below shows you two different PDF books to check out exactly how these two readers stack up. We have a very small Biology book, that is under 2 MB and the very complex D&D Monsters Manual.
