More Choices = More Love

I love Sandy; I couldn't manage without her. But without disloyalty, I sometimes think it would be fun to have some other choices of personal assistant: a faithful robot companion, say, or a lab-coated Igor (are my geek credentials showing?). . . each scripted differently, of course, but on the same basic model. I think people like to personalize, even just a little. And when I realize how "real" Sandy is to me, and to the people who know she works for me, I wonder if you couldn't generate even more loyalty by playing to that anthropomorphizing impulse.
