SD Card Issue
I also keep all my books on a SD card now to avoid issues if a reset is needed. I was in the airport in Tel Aviv and dropped my touch on the carpet. It caused a factory reset (some internal switch or memory card got jarred?) and I lost the books I had loaded for the trip.
With the new firmware and now that my books are on the SD card, after a few pages, it book marks the book and closes it.
I also have issues on all firmware versions with dead taps followed with double page turns on the next tap. Also see on occasion, repeated dead forward taps that require a back tap to reset state so I can go forward again. The debounce logic needs work since this is a basic and vital aspect of using the reader.
I write embedded software for paintball guns and wish I had the source code so I could fix the odd behaviors I keep running into.
My battery life is not as good as expected also since I keep the wifi off most of the time.
Love the reader, hoping for the best in future releases!
