How long does Pinot Noir last opened?

I've come to realize that sometimes it's best to just enjoy a glass or two of wine and either (a) store the other half of the bottle as Innkeeper described above or (b) just pour the rest out, if you really can't finish it off. Even after a day, wine has changed character. If it hasn't changed, you've gotta wonder why. In any case, there are plenty of wines out there to taste, which is why I don't mind popping a bottle for a taste and not finishing it.
