Race in fantasy games drives personality and struggle toward certain preconceptions and archetypes. You don't have to stick to every racial stereotype, but some of them are almost impossible to shed (though I'm not necessarily saying that is a bad thing). Elves are old (and thus likely wiser). Halflings are small, therefore see much of the world through those eyes. Dwarves come up in a culture where you're not supposed to whine about hitting your thumb with a hammer. Tieflings struggle with their inherent "bad guy."
As a personal taste, I'm not a fan of the Dragonborn. When I stare at Dragonborn I have difficulty earnestly coming up with anything that's strong character-wise. Perhaps it's harder to see the race in terms of "human" emotion - or what they do for fun - since they are a step farther removed from humanoid than Elves and Halflings. I don't know.
Perhaps the text pushes too far toward honor and fighting, which are fine things if you are a WWII battleship but really doesn't help with the things I find more interesting in an RPG like personality, interaction, and a degree of personal struggle. Sure the combat is just as important and fun, but it is pointless without a lot of the personality and background that makes a character feel like a vivid person. To exaggerate the point, why should the group care about a character if the most interesting thing about him is that he has an 18 Con and Str?
Anyway, don't take this as a Keithian stance that Dragonborn suck or a knock on anyone who digs 'em. This is more just a thought that's been kicking around in my head with that race. I'm sure others will have an interesting thought or two related to why it is cool or why you agree with certain things I've posted.

Here we have Vraff. I draw a blank about what this guy does when he isn't snarling and wielding a sword that looks like it weighs about 85 lbs. Contrast with Tylana the Arcanist (right). I don't draw a blank from her. Her dress leads me to believe she has traveled the realm a bit and embraced various styles. She has a bit of the smart girl vibe but she's even prettier so I imagine she never really had to push herself in the study department if she could take the path of least resistance and be a Cha-based caster. She obviously takes time to stay cleaned up, even if she is traveling in filthy caves. And the way she poses - I bet she draped her skirt and it's not the wind. I imagine she is good at entertaining herself with offbeat alchemical humor - after all, her alternative is to banter with the Dragonborn next to her, who doesn't strike me as too talkative.
