Well,thanks guys,the replies are useful to me.
I was also amazed that the small bubbles I couldn't get out did indeed vanish by themselves after a few days. But don't put an otterbox defender on your iPad with this thing on because you'll never get the defender off (as far as i can tell).
I've seen a number of comments that some installations of Zagg InvisibleShield do have the "orange-peel effect" (look it up in Wiki), although it isn't an issue with mine. I suspect it is related to how it was initially installed (some users clearly have more of a challenge installing it than others.)
The orange peel effect is very common. It is caused by the self healing Nano-technology that is exclusive to the invisibleSHIELD. It helps to heal minor scratches on its own. Some people notice it more then others do.
I have applied Zagg invisibleSHIELD to two Blackberries, two iPods, a Garmin Nuvi 780 and now my iPad. The iPad was by far the most challenging install of the bunch. I did a front screen and back install and it took much more time and patience than installing all the small pieces around the exterior of the Blackberry Curves. The mere size of the sheets made it almost impossible to manage without kinks or folds. As ZAGGchick suggests in a previous posting, it might be advantageous to have someone assist. I was disappointed with the install for the first few days because no matter what I attempted, the tiny bubbles I missed were present. In fact, I toyed with and researched methods to remove the shield. After about three or four days, voila, the bubbles dissipated on their own and the install looks pretty darned good. Be patient, take your time with the install and let the small bubbles work their way out and you can do this installation without a hitch.
I think I'm going to get the Anti Glare of this and have it professionally installed
