IMO, there's nothing comparable to MacBook Air in its price range if you are an average user. Neo is even better in that aspect. The model you cited sounds better if you are planning to use Linux and are computer literate. But if you just want something that is good (not perfect) at everything usual, a MacBook is a no-brainer.
Don't do that, just avoid answering the "non-believers" or whatever they are called. Your comments are insightful for me (and for a lot of other people, I'm sure). You don't need to prove that they are useful, just comment about your experience and ignore them. It's like arguing about religion trying to make the other person to flip their beliefs (a waste of time for everyone involved)
