But you can't configure it like the physical kindle, where page turn on either side up higher is "back" and lower is "forward." So if you're going to hold it one-handed, that either has to be your right hand or you do this weird left-arm-around-the-back contorted thing. Sounds trivial, but it's an important problem if you, say, drink coffee and have little left-hand coordination :-) GoodReader has alternative page turn virtual zones, which I definitely take advantage of.
