I was originally going for a 13" Air because Im a multi window user and not used to small screens. But after trying out an 11" today using fullscreen mode I'm surprised how much more adequate the screen was simply by pushing away those extra pixels that the OS takes up. I wouldnt say the 11" screen feels "huge" but it definitely feels more usable and now I'm leaning back to going 11". How about anyone else? Are you planning on using fullscreen mode more often and is it influencing your choice of screen size?
