My experience with electronics tells me that when I get a new piece, I need to make sure there is a screen protector on it from day one. Trouble is, Apple does not sell screen protectors for the iPad at their retail outlets. That put me on a search for the best screen protector, but my search just brought up more questions. What’s the difference between those sold on EBay for 99 cents, and those sold through Wal-Mart for 19.99? My experience with the lower quality protectors is a lot of bubbles on the main part of the screen.
