Oh bosh. Of course they aren't useless, they don't get around as good as a 4WD obviously, but will do just fine in moderate snow. Some weight in the back and knowing how to drive in snow helps a lot, and a locking differential helps too.
A 2 wheel drive truck around here in the winter is actually worse than useless ... if you manage to get it out of your driveway it is hazard to other drivers.
As far as a locking differential goes I think it is almost useless as well. My truck has an electronic locking differential and I often try locking the diff when the truck can't move on account of two snowflakes on the ground. I've yet to find a time that locking the diff made enough difference that I didn't need to engage the front wheels.
Once the roads are plowed and salted, a two wheel drive truck can get around.
