The use of a MacBook is that it makes doing work much easier and fun. They made it very easy to understand and very easy to get to things because they are just in your side dock. People can also work the hole day on it without being scared in will fall out because the battery is dead because it can stay up to 12 hours instead of the normal 9 hours. If you have to leave quickly but still have to save something thats no problem because it the MacBook can save a lot very fast.
