Congrats on your purchase, the Air is a lovely machine. I am glad to hear that you are not having any of the heat issues that plagued the 1st Gen Air. Keep us posted on it's performance, I am considering one as well.
Let me be the first to recommend the Invisible Shield. The fit was amazing on the Air and install was easy as pie. There is a thread around somewhere with post-Invisible Shield photos. Shame of it all, was that I ended up removing the shield to return the Air.
