P.S.
I should have mentioned that an LCD screen currently becomes very
expensive if larger than about 40 - 45 inches. Thus, a plasma TV costs
less for a larger screen than approximately this size.
Second, I should have mentioned that the manufacturer of the rear
projection TV that my daughter bought claims a horizontal viewing angle
of 70 degrees on each side of perpendicular, and a vertical angle of 30
degrees each side of perpendicular. I did not actually check this angle
out at her house, but could easily see that the horizontal viewing angle
is far greater than some rear-projection TVs that I have seen in years
past; some of these required nearly a head-on view to get full
brightness and contrast.
Third, I should have mentioned that I don't own an HDTV. I am waiting
until Xmas 2008 or until Feb. 2009 to make a choice. Therefore, my
opinion previously expressed is based on shopping at local stores & on
the IEEE article.
The lamp warranty was a big factor in my daughter's choice of the DLP
TV, as well as her desiring a very large screen.

My two cents.
If it is a choice between an LCD or a plasma, I would choose LCD.
This opinion is based on a lengthy article in the IEEE Spectrum
magazine of 1/2 to 1 year ago reviewing the available HDTV display
properties. According to that article, the LCD has an expected
lifetime of 5 -- 7 years whereas the plasma display is about 4 years
or so. The plasma display gradually gets dimmer and changes color
from day one but is not noticeable for about the first 4 years when
incorrect colors become a problem. In addition, the plasma is bulky
and requires a lot of energy. The article suggested that the plasma
technology would fade away as newer technologies become available.
The LCD suffers from failure of the backlight. There is a coming
technology that provides an individual backlight for each crystal
(pixel) that is promising but AFAIK has not arrived on the market yet.
My daughter bought a 61" rear projection HDTV a few weeks ago after
doing quite a bit of research. I am surprised how much improved the
display is from those I have seen in the past and how thin the display
is. It's depth is 15 inches and weighs 75 pounds. The problem with
the projection TV is burnout of the lamp. This occurs in about 4 -- 5
years and is expensive to replace if possible -- on some models the
lamp can't be replaced. She got an extended warranty that covers lamp
replacement for 6 years at a cost much less than the cost of the lamp.
In case you're interested, the model my daughter chose is a Samsung
HL-T6187S
