Well, on a Netbook I could not get anything working. The videocard is not up to it. I guess for simpler things it might be ok.
I could not find any game programming examples after installing XNA. I could not find a lot of working examples on the website that goes with XNA. There are however twohundredthousand plus users on the forums there. there are a lot of games being made but I could not find a lot of sourcecode and help.
I think I will stick with Java.
