After years of Windows I bought my first Macbook Air a few weeks ago. My 11 year daughter is a little nerd/bookworm who loves coding and doesn't like to use any of our other PCs. I was going to buy her a Chromebook for Christmas but have decided to buy her a Macbook Air 11 inch but a few years old maybe a 2010-2011 for her first computer. Is it worth it to buy one so old? It will get light use and I am not worried about space and ram. I just don't trust her with a brand new machine yet. Are Ebay and Amazon good places to look?
