I think some supermarkets fridge their eggs, some don't here in The Netherlands. However, I have never seen anyone not fridge their eggs at home. In fact, it seems crazy gross to me to keep eggs outside of the fridge at room temperature. I wouldn't want to eat an egg that wasn't stored "properly" (i.e., our definition of properly).

And it's better for the egg not to. You can use it right away if you don't keep it refridgerated. A cold egg behaves different in cooking (though I forgot the details), so you have to take it out of the fridge 10 minutes before you use it.
To me, the clincher is that supermarkets don't store their eggs in the fridge. If refridgeration was important, supermarkets would be required to do that. Also, despite refridgerating their eggs, the US seems to have a lot of salmonella cases.
