Stuff like this JackPC is a little high concept for the average hAX0r but it seems like an interesting little tool. It's basically a thin client PC with USB and VGA-out as well as some audio jacks. Plug it into an Ethernet port and it basically can be used as a virtual computer in a shared server environment. The media ports make it a compelling little addition to a home audio/video set-up, but that would require programming and math and math is hard.
