No matter what we suggest, they have the mold already built for testing, so they will do as they want. Also, people have so many suggestions that is impossible to satisfy everyone. With that said, I personally don't want something similar to a Pandora.
The main purpose of GPD is make cheap devices, so the more accesories they include, the more expensive will be, so if they add lots of things and device cost 250 or 300 US Dollars, how many people here is going to get one? I personally don't. For a expensive device we all can get a shield.
