Don't think keywords and SEO for your domain, even if that will be one of your traffic building strategies, think branding and memorability. As I write this the website eyeglasses[dot]com is ranking on page #3 of Google for the term "eyeglasses" so having a keyword heavy domain is not necessarily a slam dunk for SEO. Think of a name that is creative, memorable, innovative. You're selling your products to people, not search spiders.
That being said, you certainly CAN have a cool, memorable name with a keyword in it...I'm just saying your decision shouldn't hinge on that.
