Getting Green on Computing

I've been following a lot of news about conserving energy lately. I
feel a tinge of guilt that the PC I'm using is contributing to
generating more greenhouse gases. It's not so efficient, is why.
That's why I've been looking at some sites that sell power-saving PCs.
Given that these PCs aren't that powerful, they are adequate for most
of the common things we do with PCs. I'm not really editing videos or
pics, so I guess a 1GHz machine is powerful enough.

The DSL (Damn Small Linux) Bargain machine is a good example of what I
would want. You can check it here:

It runs on less than 30 watts of power. A 14-inch TV probably sucks
more juice than this baby. It accomplishes such a low power draw by an
ingenious combination of parts. It has a low-power motherboard and a
fanless chip, flash storage (no moving parts, less energy needed), and
an operating system that's frugal on RAM. Its only $245, plus $75 for
the 1GB flash drive with DSL already installed. If only this thing
could be shipped to the Philippines! I'd love to get one for
Christmas!
