I love DecalGirl skins, but I wish they covered more of the iPad 2 back. I'll have to go with some other form of protection unless they redesign their iPad 2 skins (have a PhantomSkinz matte back on the way to try... and if I hate that I will try an iCarbon).
Anyway, definitely get the matte. Coupon code GOMATTE usually gets you the matte at the regular price.
