Alternatives
I've used Zagg in the past...ipods, phones, watch faces. I have strayed away from it for a few reasons. The tackiness that they promote unfortunately does not lend well to a touchscreen environment....especially where you need the smoothness of gestures. There is a potential for yellowing...hope they have corrected this. Lastly, Zagg has a very good product and depending on the design of accessory (i.e. closeness of fit to the device) the thickness of their skin make insertion and removal..."not effortless".
I have since branched out to other brands like bodyguardz and best skins ever. I currently have the Phantom skinz on my Atrix (matte on body...clear on screen)...loving it! Easy installation too...15 minutes or so.
Just my 2 cents

EDIT: I meant to say Phantom Skinz
