Hello! I'm planning to buy a used Macbook Pro. There's a 13''inch one for $600, but it's the late 2011 version. I'm not sure if it's wise to buy a laptop that's already 5 years old. Also, would the specs still be better than laptops from other brands around the same price range (but newer)? I'll be mainly using it for school (ie. Microsoft) and web browsing/ youtube videos. Thanks! I'm a total noob with computers.
