Earlier, I posted a
review on using the DR in academia. I'm linking to that post here for posterity because it will probably get buried in that thread. Also, here is a video showing the stylus response rates. I wanted to post this because while I find the stylus invaluable and the lag time perfectly acceptable, not everyone appears to be happy with the response time eink offers. Hopefully, this well let the curious judge for themselves.
Edit: By the way, this is the professional stylus at work. It is much more comfortable to hold than the default stylus that comes with the DR, and has an eraser and extra button (that are not yet used by the DR) for possible function expansion. The advanced stylus should be just as comfortable, but I haven't tried it. US/Canadian customers can
get them here.
If the youtube link does not work, you can
download the video.
AFAIK, the DR is the only eink reader among those currently in the market or announced to appear this/next year that supports writing on an eink screen (
edit: not true, see below), so this is probably as good as its going to get.
Update: Muhuhahahahahaha.
