I suppose it’s not surprising that in a forum full of tech enthusiasts that we find people advocating the superiority of one device over another, but I believe, as others have said before, that in the real world people should (and I believe most people do) focus on what they want to accomplish and then pick the tool best-suited, rather than focus on the device and attempt to adapt their life to it. A device is only a means to an end, so any kind of allegiance to one over another makes zero sense.
Each type of device—iPads, Mac desktops, and Mac laptops—have their own set of unique significant strengths and weaknesses (some circumstantial, some inherent). And the world is full of billions of people and probably just as many different sets of needs and preferences. Because of these two facts, it would be pretty insane for anyone to say with certainty which device is better for people across the board. Probably/hopefully most people here are not making that statement, but all too often some people are. And on both sides. People who say that iPads cannot be a sole device for a lot of people, and people who say that Macs are only for those who are “stuck” or “antiquated”, are two sides to the same presumptuous, narrow-sighted coin. They both project onto others their limited view based on limited knowledge.
That said, the iPad is the newer device and still seems to be in its formative years, so its full capabilities aren’t currently as well-known by everyone (and it’s future capabilities aren’t known by anyone except probably a couple people at Apple). So it’s good to spread that information among the peoples. And it’s fine to make device suggestions, and fine to conjecture about any and everything, but these sweeping statements are at best silly, and at worst spread misinformation.
