A:Answer I just purchased the most recent MacBook Pro from a 2015 Air. From a screen point of view, I don’t see a major difference from the 2015 Air. Most value from the upgrade comes from increased processing ability. That said, the Pro is a bit chunkier than the 2015 air. It is by no means a heavy laptop, but you’ll notice a size change. Everything is just a little thicker, from screen to base width. I bought a new case but the old laptop sleeve and bag still works fine from my old air.
