It might not be the first notebook accessory you reach for, but the OnAir GT mobile HDTV receiver is certainly one of the coolest, letting you watch high-definition and analog over-the-air and digital (QAM) and analog cable television broadcasts on your laptop. Distributed by Autumnwave in the States, this little black box draws its power via USB cable and delivers video through an included A/V adapter cable, quickly turning your system into a TV with full DVR capabilities complete with EPG. You can hook up a console gaming system to the device as well, letting you play games directly on the laptop screen. The OnAir GT retails for $179, but if you’ve already got a notebook capable of displaying HD resolutions, this is a cheap way to watch high-def programming just about anywhere.
