Sure, it's fun to play games on your notebook's display, but it still pales in comparison to the 55-inch HDTV you've got mounted to your wall. Yes, you could connect an HDMI cable, but who wants a cord stretching across the room? The HP Wireless TV Connect lets you wirelessly stream 1080p content-- including games, Blu-rays and online video--from your laptop with no latency. You can even beam 3D content to your big screen. Still, $179 is a pretty hefty price tag for wireless freedom. Is this gadget worth the splurge?
