The problems I see with SDTV and even HDTV is simply ridiculously small
bandwidth. They're
packing 4 SDTV channels into one SATV channel, and the result is simply
horrible. Blue ray
and DVD seem somewhat better.

Maybe, but lifetime could be an issue. CRT's may dim a bit, but they perform
pretty well
even after 20-30 years.

Apparently white LED's also age in a way that changes their color markedly -
they tend to
go off the white locus and into the green. So I'm not sure what that says about
a plan
using white LED's to correct fading blue OLED's...
