Most of my reading is academic - mostly PDFs. If I cannot annotate (freehand) then it's useless to me. Now, I know, to each their own... but I want a large-screen touchscreen. Right now, the only one I know of is the iRex, but I have multiple reasons for not wanting that device.

The problem with touchscreens is they can either be glossy and let through the full clarity of the e-ink underneath or be matte and suppress unwanted reflections/glare. Both approaches have their pros and cons.
The only way to implement a pen input without a cover layer is to use something like Wacom's penabled technology, which uses electric fields to sense the pen, but that technology has the downside of dramatically higher energy drain. Not to mention dragging a stylus directly across the surface of an e-ink display is probably a bad idea.
