I am using the zagg full body protection on my n810. I must say that it is worth the investment. I am now comfortable with tossing it in my bag without worrying about getting those tiny scratches on the brush aluminum. I will post pictures later on to show where it is protected.

*EDIT

My camera quality isn't good enough to show where the invisible shield is on the n810.

face portion
On the front face, everything is covered except the webcam, light sensor and back/home key. on the same front portion, the top and sides are protected, not the bottom.

Back portion


There is no protection on the keyboard/dpad section. battery cover and plastic cover protected, whole underside of kickstand protected. on the left side, part between kickstand and speaker protected, small parts between left speaker and stylus slot protected except portion between full-screen key and minus key.

That's about it, I hope I explained well enough. Just get back to me if you have any questions. I really gotta get me a camera

Thanks
