There are so many things we love about the new Xbox 360 dev kit unveiled at this week's Game Developers Conference and due out in the summer. In addition to its sleek black-and-blue tint finish and some stylish etchings, it also boasts 1GB of RAM, or twice what is found in the retail model. Beg all you want, this gorgeous piece of hardware is only for those who make the games -- for now, at least.
