I have a weirder holding scenario, in which I hold it much like I normally would a book, but stick my pinky finger in towards myself and let the weight of the Kindle rest on that.

I often complain about it, and this Oasis appears to be an upgrade, but I have the same problem with books as well. Adding the physical buttons in is a nice feature that I've missed from my earlier Kindles, as it at least means I won't have to move my hand while my Kindle is precariously balanced on the aforementioned finger for every page turn.
