Portable Data Collection Terminals?

Manuka asks: "Does anyone know of a good system that is reasonably rugged, about the same size and dimesions as a notebook, only with a touchscreen panel facing outwards, rather than inwards (keyboard optional)?

I've had a helluva time finding anything like this, the closest I've come is the NemaLITE system from Laversab, which is beefy, 10 lbs, and more than twice what I'm willing to pay for something like this. It does not need to be excessively powerful, as it will be running a basic database application. "
