Here's a funny thing...I took my work 13" late 2010 Air to get a new charger b/c of frayed cable and a rubber foot that came off and I lost it. I thought they would just glue on a little foot, but nope, got a whole new bottom. Apple said they don't just have the rubber foot to put back on. :shrugs: All under AppleCare, so np. Actually glad I got a new bottom on it since there were some dents in it from something I did to it...
