I'm betting that there will be silicon skins available for this from third parties. That way you can change the color and also keep the Kindle a bit cleaner and protect it from minor bumps and scratches. But the first thing I'll be looking for will be a screen protector.
Personally, I like the design, I may be oldish but I love the retro look. The color not so much but I think it'll be easier on my eyes in low contrast environments.
