Serious question, has anyone looked into such a radical upgrade? Ex Gf's 2010 MBA died. And ive noticed the cost of a 2011/2012 MBA system boards on ebay isnt too bad. I have studied the ifixit teardows, and have come to the conclusion the chassis is the exact same on all MBA's 2010/11/12 model years. The screens are the same, the batteries are the same, the cooling fan, speakers and SSD are the same. The only differences i have found so far, is the battery connector has shifted to the right on the '11/'12 models. The antenna cables on the LCD's are abit longer on '11/'12 models, and the left speaker is of a slightly different shape on the '11/'12 models compared to the 2010 model (13" only) The rest looks to be the same even the connectors on the system board for the all the parts (fan, speakers, microphone, power board, display, touch pad and keyboard) another matter if it works. (ie apple may of changed the wiring pin outs).
