1) Pinched by the very bottom corner edge in one hand (right or left), one or two two fingers behind. The reader resting on the ring or index finger taking the weight. Swipe or tap the very bottom corner with my thumb (and bring up the options menu a lot :P)
2) Either hand wrapped around the back with fingers on the top edges and 2 sides. I could hit the page turn bar at the very edge of my jetBook using this method. I have to 2 hand the KTouch or else I'm bringing up the options menu again.
3) Held by the very top corner in my left hand. Fingers on the back, thumb near the top left corner just below where the top bevel meets the side one. Swipe thumb to turn the page. Again my jetBook bar would support this. I'm almost getting the hand of swiping right to left to advance but a downswipe on the -left- of the screen to advance would be handier.
4) Sideways laying in bed where the long edge sits on the mattress
.
5) Other left handed thumb on the left bevel fingers on the back variations.
I would really like to have a downswipe/upswipe anywhere on the screen to be added in. Down = go forward, Up = go back a page -- including diagonals for less than perfect swipes. That would make left handed thumb swipe page turns far less awkward.
