I love taking my mini 9 too school. When I take it out everyone goes ,"wow", and then when they see that I have SL on it they go crazy.
My teachers don't mind much and when my teachers aren't looking I just log on too my city's free wifi and play games or surf the web (preferably this site
Now I'm thinking of upgrading to a mini 10, more or less because the keyboard is much bigger and easier to type with and it has GPS.
Bad thing is that it will put even more
weight in my already overstuffed backpack.
