I had the anti glare PS on my iPad 1, still going strong. I decided today to get a protector for my new iPad... I went with the Crystal instead of the AG due to the hires screen. All I can say is
wow, this thing is so good you don't even know it is there. I have tried other type of protectors that you apply wet, they suck in comparison. You literally can not tell this is on here. I guess it helps that they installed it for me at PS... if you are in the LA area (Burbank specifically) I suggest you check them out. The $5 installation price is WELL worth it. No bubbles and it is aligned perfectly.
