I had a nice experience with Apple support. I sent my wife's MBA to get the battery replaced (13", 1.8 GHz C2D, 128 GB SSD, 2 GB RAM). The cost was about $140 plus shipping. A few days later Apple gets the computer and tells me the logic board is also bad. I believed them because my wife had reported some weird freezes that sounded like logic board issues, but I was hoping it was just because the battery was in such bad shape. It would be $300 for the logic board and battey... not too bad, I thought, and told them to go forward with it. Then Apple calls and says the parts are on backorder for a LONG time... So they just want to send us a whole new (well, refurb) MBA for the same $300! It's significantly better in every way. E.g., 1.7 GHz Core i5, 256 GB SSD, 4 GB RAM, is a little lighter and various other little numbers are better as well. I'm pretty happy! Then computer even comes with a year of support and it elgible for Apple Care. (The only potential problem was that the new OS doesn't support PowerPC apps. For my wife that meant an upgrade from Office 2004 to 2008. Fortunately we already own an extra copy of 2008, so that was no problem after all.) Thanks Apple!
