I ordered a K3 Wifi on launch day. This was just for my own use; I hadn't been planning to write a review. A whole lot of reviews have already been written and it's not worth my time to simply be one of the crowd.
I got one and I've been using it for about a week. I'm returning it. They made a number of compromises in the hardware design in order to create a smaller device, and I'm not happy with the changes.
The page turn buttons are too small; I consistently have trouble hitting them the first time. The keyboard has been shrunk to the point where it's too small for my fat fingers. And when using the joystick I keep accidentally pressing another button while pressing an arrow key because the buttons are too close together.
I know they wanted to make a smaller ereader, but there is such a thing as going to far.
