Well, I always liked those "persocom" things in the Chobits Anime except mine wouldn't be flawed due to a limited processing capacity like most of them in the anime or be childlike and borderline retarded like Chi or have her off switch frustratingly located in her vagina.
Also, she'd be able to compose super-cool Japanise pop music like that show's themsong. And she'd have to look cute in a maid outfit!
But mostly really I like the name "Persocom," it has so much less baggage then "sex robot"!
