I have a generic Wacom Penabled pen (a real, pen-sized stylus) that works fine on the edge (and originally, my iRex iliad.) Both of these readers come with the same irritating, uncomfortable little twig of a stylus. However, I discovered a difference in operation with the generic pen. To use the generic Pen on the iLiad I have to remove the little twig-stylus from its holder, because there is a switch in the holder that turns off the Penabled screen sensor to save electricity. On the edge this isn't necessary. With the stylus in its holder the generic pen works fine on the EInk screen. It would seem that the Penabled sensors are always running. So, it occurs to me this could be a contributor to the less-than-expected run-time on batteries that some people complain about.

I actually LIKE it this way. I will generally keep the edge on a charger at home and at work and only remove it a couple hours at a time to go to meetings. I'm happy to be free of the pen gymnastics on the iLiad (stylus in? stylus out?)
