I was not keen on taking on DH's surname when we married, but he was very very strong in his feelings that he wanted me to, and so I did. I am content that I did this now and am happy that my sons have the same name too. Painfully traditional, but it's all fine with me.

A BB member once told me that should she and her DH have a boy, they will give him DH's surname, and should she have a girl, then her surname would be passed down. I really really liked this sentiment.

I have lived in a south american country where it is the norm to have mother's and father's surname. Not hyphenated, just two names, mother's first then father's.

Do what feels right to you. But I guess you might have to get used to correcting people.
