Has anyone used this: http://www.amazon.com/Moshi-iVisor-...C5RC/ref=sr_1_1?ie=UTF8&qid=1305011215&sr=8-1 I have a few questions: Is it easy to take off and remove, without leaving marks? Does it work on the ipad 2?(I assume the screen and bezel is the same size, but what about the camera/light sensor). Is there a better removable anti glare screen cover? Does it really help with viewing out in the sun? I really don't want something permanent, just something I can throw on when I am out in the sun or going on a trip where I know I will be in the sun a lot.
