This is a USB TV tuner from MobiX. It definitely has its advantages and disadvantages. Here are the goods: it's ultra-portable, USB-compatible, has DVR capabilities and records in a common MPEG2 format. And the bad: It looks stupid as hell and it is expensive, nearly $200 dollars expensive, and it has to be shipped from the UK. Need to watch TV that bad? Your call, I guess.
