I've been contemplating getting rid of my iBook G4, or at least upgrading and regulating the Book to a desktop, and getting an Air. I've been wanting to find a used Air on eBay or somewhere similar where I could just get a slightly older used one and save myself a little money. The only problem is, I have no idea where to look! All the ones that I found that don't require significant repairs aren't much cheaper than a brand new laptop...and they all seem to be at least 2010/2011 models. What year did they start production on these laptops? That would probably help me in my search...does anyone know?
