I am a Kindle addict but when I found out the new Kindles didn't have 3G, I decided to look further... especially since I need a new GPS in my car (an update for the Prius built in GPS would cost me over 200 bucks and I don't know how good it is).... so, do you think that the A100 would really work in my car as a substitute? Can I see the screen or is it going to be too shiny? I know the antenna isn't that great, but do you think its good enough. I mostly travel in CA and NV. If you are using it in your car, how are you mounting it on your dash/window? What sort of case do you recommend? Thanks!
