Trusted Reviews have reviewed the Panasonic ToughBook CF-W4

ToughBook CF-29 is the Land Rover Defender of rugged notebooks, then the CF-W4 would have to be the Ferrari F430. The CF-W4 is s semi-rugged notebook, so it's not as big, heavy and tough as its big brother. Instead it's far thinner, lighter and sleeker, just like an F430. Of course just like the F430, the CF-W4 can't take as many knocks as its more robust sibling, but that's not to say that it can't withstand the trials of life as a notebook computer.
