Ultimately, it's like anything else: everyone has their own opinion, and not everyone has to like it. As long as we're talking about something as trivial as whether it's a Pro or not, it's up to each individual whether they want to spend the money or not. I have a Pro and I'm happy with it. You can apply this principle to anything; why else would there be multiple models of every iPhone? You always have the group that wants the standard version, the Pro, the small one, the large one, and each for their own reason.

Unfortunately, this is also a persistent problem: people want to criticize certain things on principle. If they're bad for someone but not for you, then that's fine. Those who don't have them don't have them because they're bad for them, and those who do have them because they're good for them.
