Thanks for the reply palpatine and Rodster. I agree regarding peace of mind. However, I think my core question was lost in the details. So here goes:
Does putting a new piece of glass over the LCD retain the quality of the iPad3 display?
I don't want to list the repair shop - not going to advertise for them.
They seem reputable, in business since 1995, offer warranty of their work, etc. I just want to know what makes the new iPad retina display. If it's the LCD I think I could be ok going with local repair since they are not touching that specific part. They would only be replacing the screen/digitizer.
Thanks again!
