I came really, really close to convincing my husband to take my last name, but he couldn't do it.  His last name is a harsh mess of consonants that's hard to remember and spell, and my name is simple, unique, and memorable.  His last name isn't even the "real" last name of the family, since they changed it into something totally different so it wouldn't sound Jewish during some persecution.  

He did agree to take my last name as his middle name (and drop his given middle name), but somehow never got around to it.  I remind him of it every now and then (7 years later), but he just thinks it's too much trouble and isn't going to bother.  I hypenated my name, and I'm generally happy with the choice.  Our kids both have my "maiden" name as their middle names, and it would be nice if my husband had the same middle name as them, but I'm not going to fight it.  It's crazy that California made that so difficult!
