My anti-glare power support screen protector is sitting on the shelf, waiting for me to get unlazy and install it.
Need to do it, as all the smudges on the screen are driving me nuts; I prefer the look of the anti-glare to the stock shiny surface.
You get used to the change in texture in a few days, and won't even notice it after a while.
Wrt bubbles: face the fact, they are not going to go away. Each of those bubbles probably actually represents a dust particle trapped under the plastic. Get a quality screen protector (power support is my vote, installed 2 on iPads without a flaw, and countless on PDAs before that).
As you roll it into place, if you see a dust particle getting embedded, then roll it back a bit, and lift the dust particle off with scotch tape. Works like a charm. Search this forum for some fairly detailed descriptions of how to do this right; that knowledge will help a lot.
