I've been looking for a media streaming device for my house and the Popbox is probably going to be it. This thing can play supports almost any audio and video file format out there and can play content from the internet, other computers on your network or a USB device. Best of all, its an open platform so there's going to be lots of apps for it. March can't come soon enough.

The one thing they don't say though is if it supports DLNA/uPNP. I'd rather do that than play files off a network share.
