Pogoplug makes internet data sharing easy

SheevPlug - the Pogo's developer kit parent is a fantastic little device - a home server that draws under 10W with an external USB drive and has a serial console is hard to beat. http://www.cyrius.com/debian/kirkwood/sheevaplug/ has more details on setting up Debian on SheevaPlug. The best part for me is if you brick it - you can reflash things down to uBoot level and even do it fairly conveniently using http://www.plugcomputer.org/plugwiki/index.php/SheevaPlug.... It costs about $115 with shipping to get it in the US from GlobalScale and the wait is roughly few weeks, but it's well worth it.
