No, I don't, but a flat panel is less restrictive. I don't have light control. I didn't say I was getting rid of the projector! I still have a lot of hours on it. It's just that I have been replacing them every 3 years, so that would be sometime in the fall. If there's no reason to upgrade, then the panels have time to drop.
When I bought this projector, a top of the line 65" Plasma was over $4k. No you can get them for about half of that. Too bad plasmas (consumer) stopped at 65". If the Mits rp tvs can get to led, then a 90" set for sub 2k should be feasible. For most people that's all they care about, price and size.
I love my 106" screen, but I could be compelled to sit closer to get the same experience. It really depends on your room.
