No, more like:
1. Don't treat "Mac fans" as a homogeneous group, and don't attribute some random opinion to them 3 years ago, observe that one particular Mac fan has a different opinion now, and accuse "Mac fans" in general of hypocrisy. That makes no sense.
2. Don't equate "a cheap Dell laptop that does everything you need" with a MacBook Air. That is like comparing apples and oranges.
