I have the “competitor’s” tablet. My first thought was that I could use it, besides its primary intended use as a reading device, as a larger screen for the 50D. But this is not possible directly as far as I know, only if you connect it to a laptop and that one with the camera. That kills its usability for me in this case. I hope this is not the case with yours. I have used it in travels as previewing and storage device; surprisingly it knows how to render raw files. I’ve changed once the language in Facebook to “pirate English” and it called my tablet as “eye plank”
