Does anyone here use a newer Panasonic Toughbook? I'm just wondering how good they work, because I'm thinking of buying a newer one off of ebay. For all of you who don't know what a Toughbook is, it is the world's toughest laptop. The case is made out of a magnesium alloy, and all of the components have shock-dampening measures. The keyboard and pointer are splash-proof, dust-proof, and soda-proof. Some of the newer models have the capability to use cellular networks to transfer data, surf the internet, etc... Anyway, I'm hoping someone has one, and can tell me how some of these features work.
