I'd bought myself a set of Apple screen-protector.. just to... them off. I had to cut in into the size I needed, but it works perfect with both screens. Looking to them now, after almost 9 months or so, I sure can say I'm glad to have them.

Yes, maybe I use the stylus wrong, but you can see that I use my eDGe a lot.

In my experience it did not lose any of it sensitivity.
