Forgot to mention that as the RPTV is typically 1-1.5ft deep, by using a projector you will gain that distance in projection.....so you are less likely to suffer eye strain from sitting too close to the projector as you would with the TV.
Oh, I have owner both HDTV RPTV (65" Toshiba) and 3 different projectors. I will never own an RPTV again. My TV weighed 330 pounds and we had to get it ap (and down) a full flight of steps. Never again. I much prefer my 6.5 pound projector!!!!!
Oh. the one good thing about an RPTV is that they rarely get stolen if you are broken into. The damn things are just too bulky and heavy. OTOH, So they take your projector....who cares! With new for old replacement, you could get the newer model in your insurance claim!!
