With my Kindle 2, I almost exclusively turn pages with my left hand — I tend to hold the Kindle in my left, especially while sipping something with my right.

The downside, in my view, of the flipping the DX upside down would be when looking up a word, or searching for a word within a text — one would need to turn the unit upside down again, re-enable the pivot, and then type the entry.

This seems really cumbersome. I love the Kindle 2 but I might wait for the Plastic Logic when I decide I’m ready to have a larger screen and native PDF support.
