It's been nearly two years since Panasonic announced the rugged 7.0-inch Toughpad FZ-B2 tablet. Usually, that is a signal for manufacturers to retire the model and prepare for a new one. Rather uncharacteristically, Panasonic is sticking to its FZ-B2 guns and is instead giving it what is has described a "stunning makeover". That might be a bit of a misnomer though, as the new FZ-B2 looks almost exactly the same as the old FZ-B2. Inside, however, Panasonic has indeed let loose some big changes that would perhaps warrant calling this an FZ-B3.
