I wouldn't want to because I think taking your husband's name is dated and old fashioned and also because i'm a bit of a feminist. But unfortunately, my last name sucks, so I have a real problem here But since i'm nowhere near getting married anytime soon (hell no!) I don't really care at that moment.
I have a beautiful last name. It would take a lot of convincing for me to change it... I just don't think I would. And I wouldn't care what my husband did--he could keep his or take mine. I don't think I'd hyphenate; the kid(s) could have one surname be their middle and the other be their last.
I'm not in love with my last name, and I don't like how it pairs with my first name. That said, I can't imagine I would want to assume his last name, because, well, I've been living as Patrick _____ for all my life, and a change would be too weird.
And passing along my last name to any children isn't a big concern of mine. If he would prefer the children have his last name, or if he would like to hyphenate names, that's fine. Whether they have my name, his name or both names, they're still my kids. I won't feel like I have less of a connection to them because we have no name in common.
