My base model space gray rMB will be delivered today but I have some questions comparing it to a mba 11. How is watching video on Netflix or the like, does the screen make a huge difference watching video? How is the trackpad and keyboard? I think they may take some getting used to. How is the higher resolution and but extra screen real estate? I felt slightly cramped at time on my air but not too bad. These are questions to get me by as I await the UPS man!
