I like the crunch in the article.
An extra second wind is fine by me. One of my big hopes for 4e is that racial abilities will be universally useful, rather than the highly, highly situational ones we have now (+4 dodge v giants?) Everyone in every campaign can use an extra second wind.
No darkvision! Hooray! Lighting, and problems surrounding lighting, are one of the classic elements of D&D, and having a character in the party who ignores it is just annoying. Low light vision is much better.
I like the Eladrin racial feat. I'm all for giving out little bits of magic to those who want them.
The dragonborn seem alright to me. They're not classic tolkienesque fantasy, but I'm pretty sure I'll survive. And if this means that the core books will make available a character who can naturally fly, I will be a very, very happy person. Even if its only a very high level ability.
