<10 watts! That's impressive!
Do you have any stats on the loads the SheevaPlug runs at? Is that
6-9 watts under load? Is it running high CPU loads all the time
because it is underpowered?
The idle power consumption is the big area I wanted to focus on for my
next build, as we really only record 3-5 shows per day at most. My
current system (Athlon XP) idles at 97 watts and peaks around 160.
:-/ I know I could drop this by 20-30 watts easily by changing
processors within the family, but at that point an Atom would
outperform it for a fraction of the power...
The SheevaPlug sounds cool, and being ARM wouldn't bother me (I'm a
Gentoo user - I'm used to recompiling everything), but I would have to
figure out a better front-end if I went that route and used a split
front/back system. If I used my current system as a front-end, even
for just a few hours a day, it would negate a lot of the power
savings.

Oh yeah, analog is definitely good for "HD" and beyond. CRT
projectors were capable of resolutions substantially higher than "Full
HD" a long time before DVI was available or became common.
