Hey if y'all don't mind ill use this thread to ask for a recommendation. I'm using a 2009 macbook (a1342) that I upgraded with SSD, extra RAM etc. When it passes, I planning on replacing it with another old macbook. Are following models as reliable? What about macbook air ? I'm worried because the white macbook was easy to repair and upgrade, the others seem much harder to take apart.
