The battery life of the device is the biggest let down, as far as I'm concerned.
I don't get any other major problems or crashes although it does sometimes drop out of a book to the menu.
The "mystery battery hog" must be the digitizer. I have the same problem on my Irex DR800 (which has a WACOM digitizer), if I turn the screen off and don't use it for a while the battery will still be empty after about 5 days.
