The first ebook reader I bought was a Sony and it was great. I preferred it to the kindle at the time because it let me import any format file into it via USB. So I have no issues with the brand as others do. Sony has a solid presence though on the periphery of the eInk scene. My only concern with this device is input latency. Every eInk screen I've used that takes input has too high of a latency for annotation to feel as natural as pen and paper.
