It's OK but not amazing. The screen seems to have a purplish coating that reminds me of the anti-glare coating you see on eyeglasses.
In my high-ambient-light living room the reflections are still quite visible.
I'm upgrading from an RPTV that had the screens re-stacked so the lenticular was on the outside and the protective (glare) screen on the inside. This was by far the best anti-glare solution I've ever come across. The lenticular screen is super diffuse and even under direct sunlight wouldn't show any noticeably reflections.
Overall though, I'd still take a somewhat glare-y plasma over an RPTV any day.
