I wrote on my discovery of MS Reader for the PocketPC not long ago at weblogs.asp.net. I investigated MS Reader primarily for reading to my little girl at night, but found myself using it regularly for my own reading.
I will read a bit after late-night coding sessions when its not too late (that is, if its before 2:00AM) or on those nights when I don't geek. In the last month I've read Pollyanna, Black Beauty, Dan Brown's Da Vinci Code, and Stephen Ambrose's Band of Brothers. Am currently reading Lance Armstrong's It's not about the Bike, which is excellent! Funny, we actually own both the Da Vinci Code and It's not about the Bike in hardcover here at home, but it took MS Reader on the PocketPC for me to read them. Maybe its because I'm a nerd.
