I bought my father a Kindle DX - he enjoys it, but I would not be able to stand it. Call us the spoiled computing generation - but with complex graphics-laden PDFs, the Kindle can take up to ten seconds to change page. That's ludicrous and, and it alone wipes out any advantage e-ink has over backlit.

The entirety of the Kindle software is really, really slow. I'm not convinced this is simply a matter of the e-ink display - even things that do not force a full refresh of the display incur large wait times.
