My dd is 9, too. I think your list is great. My DD has wanted an AG doll for a while, she enjoys just looking at the catalog when it comes out. So far, she's only had AG books. But my mom is getting dd her first AG doll, Samantha, for Christmas. My dd would love the laptop, also games for nintendo. She loves Little House books, too. So, age wise, I think you are on the right track.
I get so mad when kids enjoy something, but then another child tells them it's too babyish. My niece, who is also 9, has had a princess themed room for about 4 years. Very tasteful, subtle, not over-the-top with characters. Anyway, she was perfectly happy with it, until her friends made fun of her. Now she's embarressed and wants a new room.
Those of us (adults) who get kidded for our love of Disney, excitement over characters, etc. get a taste of that, I guess. But as adults, we have the confidence to know that people are just kidding with us, and their opinion of us doesn't really matter anyway. But kids tend to base their whole self image on what others think of them, so peer opinions are everything to them.
Enjoy this Christmas!
