One of my users backed over her MacBook Air with her car. "Just the corner! I swear!" Her LCD was cracked and not working properly.
The repair did not go very well. Apparently you can not remove the LCD from the lid on the late 2010 model. This is not iFixit's fault though. We didn't do enough research before we tried to replace the LCD rather than replace the entire lid assembly.
Maybe a line (in bold) on the 13" MacBook Air screen repair guide that this process does *not* work for any 13" MacBook Air 2010 or after.
