I never belived in Santa Claus, its important to my husband that our child does though. What am I missing?

My parents never instilled a belief in Santa Claus in me as a child. It was never a big deal to me and I respected other children's belief. I don't feel that I missed out on the spirit of Christmas or a belief in the fantastic. It had always been my plan that when I had children that I wouldn't teach them about Santa either. My husband however thinks that it is important that our son believes in Santa. I guess to some extent I feel like, why would I instill a belief that will inevitably be dashed? Is there something that I'm missing? Why is it important that a child believes in Santa? I feel like I don't get it. Is there anyone else that feels the same way that I do?
