The category of laptop/tablet hybrids is one of the favorites among Windows PC manufacturers, including the Japan-based Panasonic. Accordingly, the Toughbook maker hosted a conference in the Land of the Rising Sun recently, where it took the time to reveal its new CF-MX3 convertible laptop. This adjustable machine comes with a 12.5-inch, 1,920 x 1,080 LCD, a removable battery that can last between 14 to 15 hours, Windows 8.1, pen support and a built-in DVD drive — yes, a DVD drive.
