Hello Everyone, When I first bought my iPad2, I purchased the ZAGG InvisibleSheild, and after awhile it developed a yellowish-brown discolouration on the edges of the iPad. (I got the white one) It makes it look like I am actually abusing the thing, but in reality its just collecting every spec of grime it acquires after normal use. The shield itself feels like the peel of a lemon, or orange. Its just annoying. ---- Now to the main question...should I just take the thing off and use the iPad without any type of screen protector, or should I order another brand such as the PowerSupply one. My main worry about having the iPad without a screen protector is that I will accidentally scratch it with my finger nail when I use it, or someone else will scratch it. Is the glass durable enough that I can go without? If I should get a new one, what brands would you recommend? --- Thanks for your help! Excuse my English by the way.
