Plug the Artec T14A USB TV Tuner into your laptop, install the software and you're watching HDTV. All of a sudden you've bypassed buying an HDTV, setting up an HD cable box or anything else.
Using its included antenna, it pulls in over-the-air HDTV broadcast stations in the US, Canada, South Korea, Taiwan and Argentina, which use what's known as the ATSC (Advanced Television Systems Committee) protocol.
It includes Windows XP Media Center Edition drivers, but keep in mind, if you want to use that, you'll also need a separate analog TV tuner installed. It's $89 with free shipping. There must be a catch. This we gotta try.
