Hello All, I have been reading these forums for awhile, but this is my first post. Thanks you all in advance for any advice. My 2012 Air (with upgraded ram) has the dreaded "logic board needs to be replaced for $755" tag now attached to it... It just seems crazy to spend that much on a 2 year + old computer. My home computing needs have become pretty basic web browsing, streaming and torrenting. A local computer shop has a used Air "Core i5" 1.6 11" (Mid-2011) for $450. Is this a good price? how does this compare to a 2014 windows based laptop in the same price range? Should I just repair my broken air? Thanks again for any input..
