Panasonic's gone on a real tear here, releasing two new Toughbook models at once. While you grapple with the implications of such a thing, let's get down to details. The new 31 and 19 Series Toughbooks are 13.1-inch and 10.4-inch models, respectively, and as far as specs go, they both pack in a 160GB hard drive, up to 6GB of DDR3 SDRAM (with 2GB coming standard), and Intel QM57 Express chipset, and 1024 x 768 resolution displays. Both come with Windows 7 Professional pre-installed, and the Toughbook 31 has a 2.4GHz Intel Core i5 CPU, the 19's go a 1.2 GHZ inside. Other than that they've both got Gigabit Ethernet, WiFi IEEE 802.11a/b/g/n, Bluetooth 2.1, an HDMI slot, four USB ports, and an SD card slot. Of course, they're also drop resistant in addition to being dust and waterproof. They'll be available starting in mid-September in Japan.
