Panasonic's W5 is one of the few ultraportable notebooks on the market that places an importance on durability and outright strength. Other companies like to say that their notebooks can take abuse, but very few of them actually get close to achieving what you might call "rugged". Panasonic actually calls the W5 "business-rugged" which is a take on their semi-rugged and fully-rugged models though it does not have to pass the same certifications. This review will be looking at Panasonic's W5 notebook. The Toughbook line is known for it's fully rugged models, some of which are strong enough to be shot or dropped repeatedly, but the W5 is part of the line's business series. These business notebooks are inspired by the design of the more robust models, but are considerably lighter and less expensive.
