This is a long story but i am going to make it short without loosing the important bits. On Feb 17 2009 i bought a NIB Macbook Air Rev A from B&H in NY ( 1.6/ 80g version )plus applecare warranty. It was on sale so i got it for 1399 plus tax plus applecare. Everything was fine for first two weeks, moving data from my back up,working on it,traveling etc. I do sales so i am always on the road. After 3rd week everything started getting different, i was experiencing heat, core shutdowns,random freezes, the usual suspects. I called applecare spoke to someone and i explained my situation in details. After being on the phone for more than hour he told me that they were going to ship me a new adapter ( don`t laugh ) i tried to explain him that it is very unlikely a power adapter issue but he insisted that they have to try all these steps in order to solve the problem. I gave my c/c and they shipped the next day. As you can imagine nothing changed. Same problems, this time i can`t even use it with clients for presentations.( keynote freezing for minutes ). I called them again, this time i spoke to a product specialist, he told me to take it to an apple store, he said everything is documented. Here comes the funny part The next day i made my appointment went to my local apple store. The genius asked me couple of questions and he started working on it. After 25 minutes he came back with a new macbook air box ( 1.6/120gb version ). He told me that my mba failed all the tests and they are going to replace it. While he was filling the paperwork one of the managers came to me and dropped the BOMB!!!. He said that i have to pay $ 400 plus tax for this exchange. This is because they don`t carry these versions in stores anymore and my mba is $ 1399 in their system ( they are buying my mba for 1399 plus tax and selling me a new one for 1799 plus tax ). I guess at the store somehow it made sense to me and i paid them $ 400 plus tax. When i got home, started to think about it, things did not make and sense so i called apple customer relations. I spoke to someone, explained her what happened. She asked my receipt number ( numbers below the bar code, starting with R ) and she told me stay online. She came back in 15 minutes and she said that everything they did at the store was right and there is nothing that she could do. Is this right? Can apple purchase my laptop at a discount price? What can i do?
