Are we talking about Tolkien style fantasy dwarves? Or are we talking about little people in real life?
Fantasy dwarves are awesome. I've always appreciated their straight-forward, grim and gritty, unrefined approach to life. Fantasy geeks are almost always fixated on the prim and proper nature-loving elves. Don't get me wrong, elves are cool (in a more obvious Legolas-from-the-LOTR-movies kind of way), but there's a certain down-to-earth (shameless pun) coolness to be found in characters like Gimli.
Then again, with characters like Aragorn, you get the best of both. The mysterious and suave nature of the elves combined with the gritty and earthy style of the dwarves, which is why the Aragorn-style character is almost always my favorite fantasy character archetype.
Of course, if we're talking about real life little people, then then the above is just fantasy geek rambling and I say that "dwarves" are just regular people, only smaller. No big deal. Although, I do find the way they talk a bit disconcerting. It sounds like an adult voice...but not... It sounds like projecting a rock concert through speakers that are too small.
