Are there any other differences other than the anti-glare protection screen? The screen doesn't really look much better to me in 2 different stores. Still a lot of glare, but slightly sharper pic. It's easy enough to take off so I am thinking about just getting the 525 for a better price unless there's some other compelling benefit to the 725.
Anti-glare is the only difference. I purchased the 725 at Ultimate Electronics for Less than Best Buy wanted for the 525. In the store it's hard to see the difference in glare, but I've read about many complaints with the 525 and glare. My 725 seems to do pretty good with the anti-glare sheild...I'd hate for it to be any worse than it is though, because there is still glare from various light sources around the house, but it's not distracting. Unless you're in a room with no light's, I'd go with the 725. I think you can buy the diamond sheild seperate for $300 if you buy the 525 and later decide you need it.
