For those of us who need to do computer work in dirty and harrowing situations, iKey has a new industrial keyboard that's "built to withstand the harshest of environments." The Membrane Keyboard has no crevices, to prevent gross gunky buildup, and a waterproof, washable surface.
The keyboard includes raised, mechanical snap-dome keys under a hardcoated polyester film that's more rugged than conventional silicone rubber keypads. It also has an integrated Synaptics touchpad, like the ones found on laptops, which can substitute for a mouse. The device is especially built to withstand the humidity and dust of industrial settings, such as a work shop or food processing company (or certain blogging locations).
