Why unsalted butter? Since it has no salt, which acts as a preservative, the "use by" date is sooner than salted butter. This means you're getting fresher butter.
In cooking: There isn't a standard amount of salt in salted butter; it differs by manufacturer. Some use up to 1/4 teaspoon of salt per stick (one-quarter pound). This means it's hard to control the amount of salt going into your baked goods.
As Charlie mentioned, I've also grown accustomed to the taste of it on toast, etc. When guests are in for dinner, I use the little foil-wrapped butter pats you get in a restaurant (also kept in the freezer, of course), which come from Sam's Club. They are salted, and more palatable to most people.
