How about a SheevaPlug? Very small, has a USB port, ethernet, and an
SD slot, and is $100. 512 MB and 512 MB flash is probably overkill for
you, but at this price, it's just gravy. Granted it is not DC, but
since it is the size of a power brick it shouldn't matter! I'm sure you
could drive the thing with DC if you put your mind to it.
I own two of these and they are very capable little units. They ship
with Ubuntu 9.04 (but not the long-term edition), and since Ubuntu
10.04's ARM distro won't be compatible with this processor, most folks
are moving to debian stable.
