Remember VIZIO's LED backlit 55-inch XVT LCD with WiFi and widgets that debuted for two grand last year and seemed like such a value? Great, now go ahead and forget it because the company's top of the line model in August will switch over to a monster 72-inch 480Hz LCD (above) with 3D, WirelessHD, VIZIO Internet Apps widget platform and Wireless-N for $3,499. If that's too big to fit your budget (or in our case, tiny shoebox apartment) there will also be 55- and 47-inch version
