I've shied away from Kobo, but from what I've seen in the vids, it looks very nice indeed. As long as the firmware is solid (or better still, can run linux) and the hardware is okay, it will be a very tempting device.
It might be important for me to be able to run night-mode with that light. I am glad that someone has shown Amazon how front-lighting is done. The PW2 will have to up its game to match this.
