If last week's ToughBooks were a little too big for your needs, Panasonic today bestowed its ultraportable W5 and T5 ToughBooks with built-in mobile broadband. The cool thing about these notebooks (aside from their slim waist line) is that they're the first rugged laptops compatible with Sprint's EV-DO Rev A network, which delivers download speeds of 450 to 800 kbps. (They're also backwards compatible with EV-DO Rev 0 networks). Both notebooks feature a 12.1-inch screen and weigh under 3.5 pounds each, the T5 however is a Tablet PC and features a touch-screen display. Both systems will be available next month starting at $2,249.
