Panasonic is a good one, my old boss liked to mess with people by knocking their ToughBook to the ground because their shock-mounted hard disk could shrug off this treatment. Really impressive, the hard disk drive is mounted in a 1/2" thick rubber gel block. I suppose the newer ones don't need this trickery thanks to solid-state storage. I can't be the only one to notice that desktop computing has come full circle, with the computer starting as a box of cards with no disk drives, to machines with multiple removable and fixed disk drives, optical and tape drives, and now we've come back to the computer being nothing more than a box with cards in it again.
