You know what is funny? I was just thinking about my old 500 today. I have been using my T3 for a few years now. Over the holidays maybe I will pull out the 500, give it a good charge and play with it. I also still have the 650 which weighs a ton, and I remember if I was reading in bed not to hold it over my face because if my grip slipped it hurt when it would land on my nose.
I don't download Kobo books on the T3 much and I kind of miss the old Sony Reader Store, but dang Sony, you do have long-lived reading devices.
