I just bought & wasted $20+ on the Photodon anti-glare protector for my 13" MBP. The speckling/rainbow effect on white pages just killed it for me even though the anti-glare was nice and the protector was well made. I've read that due to the extra glass panel between the display and the protector, it's hard to get a decent ant-glare shield. The Moshi iVisor AG doesn't actually adhere to the glass and I may give it a shot next. Anyone have one? If so, how does it work? In theory, it should work better than the Photodon but would really like to hear from someone before I drop another $40 and wait with bated breath for the USPS guy again only to be let down.
