eInk based ebook readers have been around since at least the iRex in '06. My current jetBook in the same format as the Sony here even has 4096 colors. The thing that always kept theory from practice for me was the high latency when doing the actual annotations. 150ms is too much when writing and your pen is 3 strokes ahead of the display.

Is this reader any different? Just looking at the page, I don't quite get what makes it different and HN worthy?
