I'm thinking hard about getting an 11" or 13" mba. One thing that I keep thinking about is the upcoming Airplay to Apple TV feature. Does this new feature make you want to get an 11"? Now when I am sitting on the couch, will I be watching my laptop on my flatscreen making the smaller screen size of the 11" less of a factor when deciding between the 11 and 13? What do you think?
