The WD-TV live is now a few £s cheaper from scan at £96.59 in the today only section. Normal price is 98.92 which is still pretty good.
insert marketing blurb:
"HD video, photos and music - they're on your computer, on your USB drives, on the Internet, but how do you enjoy them on your TV? Now it's easy! Play a whole world of Full-HD, 1080p media on your big screen TV with the WD TV Live network-ready HD media player."
Basically if you don't already know what this is, if you have a computer with videos on it upstairs with this you can watch them downstairs.
