I got the iPad screen protector pack ($2.99 for 3 pack) from Amazon (
http://www.amazon.com/gp/product/B003D8GAA0) , cut it to the size of both the PE screens and applied them as instructed. Not a single bubble on any screen. They are perfect. I like the feel on the tablet side and the stylus movement is now very smooth now. Since the protectors are glossy, the reader screen has become shiny. Later, if not comfortable, I may get rid of it from the reader screen.
