I am pretty sure I don't need or want any of these. It would be useful to be able to do word searches, but if the cost of that is a keyboard, I'm probably not interested. A small external keyboard might be useful but I'm pretty certain I would never carry it with me so it would have little value. An on-screen keyboard might be a good thing but I can live without it if it adds much cost. Sorry, but I'm pretty happy with my Reader.
