Credibility A lot of Internet users tend to trust a company with their own domain a lot more than one without. However, for others this is not relevant. What do you think of companies that can't afford their own domain name or are hosted on a free server? Serious businesses need to have their own domain name.
Easy to type A short URL is easier to type in the browsers address field. It's also easier to add it to your SIG file or to write it on your business cards and print it on your business letters.
Protection Once you've registered your domain name, no one else can take your name and register it. Try a Domain Name Query to find out if your desired domain name is still available.
Affordable The registration of a .com domain with InterNic only costs USD 35 for one year. The first two years have to be prepaid.
