DV Hardware takes a look at the Freecom DVB-T USB Stick:

Freecom's Digital TV DVB-T is a terrestrial receiver & radio input adapter stick for PC's. It is about the same size as a USB memory pen, making it the world's smallest digital TV and radio receiver, allowing access to digital TV and radio programs anywhere, subject to reception, topography, objects, weather and Freeview coverage. However most of these restrictions are resolved by simply connecting an indoor TV aerial into the adapter between the aerial cable and the stick itself.
