I got my PRS300 out of the closet today. . .
And I started reading a book on it that I had neglected to read in the past. Recently, I've been e-reading on my Droid Bionic phone. Not bad as an e-reader, and it certainly is convenient, allowing me to buy books from a variety of disparate sources. However that PRS300 is built like a tank (and weighs almost as much).
BUT, I had forgotten just how good a reading experience that little Sony device provided. I miss the touch screen for turning pages though, so I might try to find my PRS350, it's around here somewhere. But in the meantime, I've found the little lighted case for the 300, and I think I'll use it a bit.
