Since I only need it to project movies, the "wall projector" is the only way to go for us. The "flat screen tv's" are just the new replacement for tv's, and probably cheaper to mass produce than glass tubes with their accompanying high voltage chassis.
At todays prices, and for those of us who only want to watch pre-recorded material, flat screen and plasma tv's make no financial sense whatsoever - especially when the picture from a five lb. projector is BIGGER and BETTER!
Yep. My projector is only 3.5lbs and I use it for everything - I don't own any tv's or monitors. The only drawback is the high cost of replacement lamps. I had to order one today and it was $325.
