Nice article on changing one's name when becoming married. The conclusion:

...the beauty of the contemporary name change is that you don't have to formally decide. You can keep your name professionally and socially, change your name for the purposes of school lists, or airline tickets, or your husband's presidential run—in short, you can maintain an extremely confusing relation to your own name (or names).

All this is reassuring to me since I am not planning on changing my name. To me, it is important to retain one's own idenity and not have it lost within the name of one's husband. Granted, husband and wife are merging thier lives, but they are not becoming anything more than leagally related to eachother. I think also my view is effected by the fact that Jason and I have lived together for 2 years without sharing a name, but sharing everything else, and marriage really isn't going to change any of that.
