Overall, I like the thing. I'm new at e-readers. Haven't read much the last 2-3 years; been listening to audiobooks on the road and on the tractor, but I began to miss reading.
It seems sturdy enough built, fits well in the hand. I unintentionally toggle the page turner sometimes, but controlling a paperback or hard bound with one hand can be a problem also. Surprisingly, the page size (which I thought would be too small) works out well.
Nice to be able to pack a whole library and pick whatever (light, heavy, fiction, etc.) fits the mood.
I see some necessary compromises:
..I'd rather have a large keyboard, but I'd rather have a physical keyboard than one on a touch-screen.
..The light tan background robs some contrast with the letters in dim light, but probably is a help in bright sun.
Mostly I have a thing against special batteries. I would accept a cylinder along one side to take some rechargeable AAA batteries, as a trade-off for the nice thin profile.
