Generic Names Or Brand Name Domains?

I know that a number of people seem to think that your domain name really must be some generic name like "cars.com" if you are selling cars. Witness, for example, how much money those generic names are being sold for. But seriously, if you were looking for a car, you'll probably already have some brands in mind, and you're more like to try out things like generalmotors.com or toyota.com rather than just cars.com.

For that reason, I personally feel that a domain name that matches your brand name is very important. The very name that you use to advertise your product is the name that you will want for your domain, because that is the first thing that people will try in their browser. It is also the easiest thing for them to remember, and whatever that is easily remembered, will be more likely to be tried out than the obscure domain name.
