<img src="http://tctechcrunch2011.files.wordpress.com/2007/01/U2 TV tuner is a hardware dongle that gives your laptop or desktop TV via USB. The cool little device has support of external antennas to boost reception, and is powered from your USB bus. The U2 monicker does not mean it's red and black.
The included software allows you to record Mpeg-4 at 320×180 (not so hot), but there might be ways to work arround that. It also takes advantage of IEPG, which allows you to schedule recording times, much like VCR Plus.
It should be available for about $105 in Japan, though no word yet on if we'll see this little critter stateside anytime soon.
