Personally I chose not to hyphenate my last name because my husband's name was already too long and French so it's also hard for most people to spell and pronounce. If I had hyphenated it I would have had a 16 letter last name. Ten letters is already annoying enough!
On a side note, I did try really, really hard to convince my husband to take my last name, for the above reason. Of course I can always tell telemarketers just because they can't say my name!
