Guilty as charged, lol!
I really like Celestia. I think she's warm and caring, clearly loves her subjects, student and sister, and wants to do what is right for everypony. I also love that she is shown to have a sense of humour, and that she's not flawless; it makes her more believable.
Not to mention the animation of her - she's so beautiful and regal.
And really, who wouldn't love little tiny filly Celestia?
