NINTENDO DS
The Nintendo DS is a great console and it's great fun. It's a touch screen console with sticks to touch the screen with and a microphone that some games use. Nearly all of its games are ones that girls would like. Remember though if you are planning on buying a Nintendo DS make sure you get some kind of screen protector because the amount of time you will touch your stick on the screen it will get so scratched that you won't be able to see the game that you are playing.
It comes with built in Wi-Fi access if you have a normal wireless internet access point (ask Dad!) to allow you to play some games with other girls around the world. Nintendo make some great games for girls and this DS (Dual Screen) is a great portable handheld console.
Its also available in silver, but I love my pink DS!
