I changed my Kindle's name, but I always refer to it as "my kindle" so I suppose I didn't really name it. Same with my iPod, it has a name, but I don't call it by it.
Oh, "spelly" and "clickers"? Hilarious!
I still think that my point about boats is valid though. They're objects. And I've heard many people call their cars by an affectionate pet name. It furthermore stretches the "they're objects" argument when people talk about their cars using the female pronoun. (She's a beauty!)
Would you fault a child for naming a doll or a teddy bear? I mean, they're just objects.
I can't fault people for naming something they have affection for, it's human nature to want to personalize things that we really like.
