The children having men's names is also interesting. I didn't take DH' name. (And I've used a version of the "that's okay Karen, I'll just call you Nancy from now on" suggestion from page 1, successfully!
)
However both DC have DH name. Both DH and I are fully aware that this is not a particularly feminist decision and it was discussed at length. DH strongly wanted us to do something like give DC1 one name and DC2 mine. Or perhaps split it by girls/boys. He did have a real sense that he wanted a child with his name - which we both attributed to a slightly irrational but nonetheless real feeling generated from spending his entire life assuming his children would have his name.
I was the one who resisted giving the DC different names. Intellectually, I think his boy/girl suggestion was a good one. However, I couldn't face it. I took so much heat when I refused to take his name from the weirdest corners - family, friends, colleagues and random strangers - that I didn't feel I was willing to fight the fight about why we were giving the DC different/my name. I completely accept that was not a particularly feminist decision, and I own it as such.
DH still makes name noises. He's repeatedly said if the DC want to take my name in due course he'd be understanding, especially as his name isn't english and is weirdly difficult for English people to manage (it's not a particularly complicated foreign name IMO). He's even more supportive of the idea of DD taking my name down the line if she lands up being the rampant feminist I am! 
Broadly though, I agree. If you choose to take your DH name, I think it's sensible to at least consider what decision you make. We don't have to make decisions that fit with all our feminist goals all the time, but the lack of thought before 99% of my friends rushed off to change to Mrs DHName always disturbs me.
