I've been wondering about that too. Now that I am older, ambient light isn't always sufficient for me. I go to a lot of theatres, and the house lights are usually dim, and it's difficult to read a paperback now. I had a PalmTx a couple of years ago, and I loved being able to read easily during intermissions.

The PalmTx is no good now; I am on Windows 7 and they won't speak to each other to update. I am very interested in the opinions on ereaders.
