What are the advantages of buying a leather computer bag?

I am getting ready to buy a computer bag. I have found a nice leather bag that I like, but it is rather pricey. I want to know what advantages a leather bag offers that justifies the extra cost.

plastic and other material keeps the warm after the computer shutdown, and its bad. leather some how frees the computer from warm that sometimes has after being used. also some leatherbags are strong and hard to prevent damage to the pc. also looks nice
