  Both technologies require the same kind of bulb and both supposedly don't have burn-in issues. However, no one to date has really been successful at bringing out a LCOS RPTV set. The Toshiba sets had to be pulled from the market (reliability problems -- pictures developing strange anomalies, and high rejection rate at the factory for the chips). I saw, at CES, a very reasonably priced JVC rear projection set (1080 x 1920 chip) that looked good, except for black level.

  As for front projection, the LCOS/DILA sets that I have seen that had good pictures were very expensive and utilize expensive Xenon bulbs. The cheaper projectors have very poor black level and so they looked quite bad in dark scenes. LCOS is inferior to DLP in this respect. The LCOS technology that looked pretty good is the Sony Qualia, but at $28,000, with a $2,000 bulb with a really short life, I will have to wait for the trickle down of techonology.

  I was told that DLP bulb life is about 8000 hours. If you watched the set 6 hours a day that's over 3 1/2 years of life. Personally I couldn't possibly watch that much TV. And if the bulb has to be replaced its an easy do-it-yourself swap out.... at least in the Samsung sets.

    Wouldn't it be great if you could swap out the chip too, so you could essentially upgrade your tv via the chipset. :)

    I'm sure they would rather you just buy a new DLP RPTV...;)

  I Like my DLP Samsung.

  Bulb is covered under the warranty period and $220 off the web.

  I don't know enough about LCOS to render an opinion. I like the fact that a 43 inch set fits in my living room without taking it over, weighs 67 pounds and I move it when I want to.
