Hi, I just got my 11" i3 MBA for 2 days. Just found that it is a bit loose in the hinge. like the guy at this vid http://www.youtube.com/watch?v=ZqNL537opSQ But for me it is a little tighter. I need to put the keyboard side at 90 degree before the lid collapse to its widest position. When I close the lid it is normal. Is this a normal? Or should I need to replace? I bought from Apple Online. There is no official Apple Store in my country.
