We'll due to groceries being essential, iPads not.
The general idea's the same. Technology and advancement in technology is just as essential. Preference for different options in technological advancements and products is going to create discussions (hence the forums).
Having different types and brands of peanut butter available is going to spawn different opinions on which people prefer. If you overhear a random person discussing with another person their preference for chunky peanut butter over creamy peanut butter, doesn't automatically give you need to butt in and say "who cares" about their preference or their discussion. It's a pointless interjection in a discussion that doesn't really include you, on top of it being pretty rude.
We all want to share and discuss our opinions and it's obvious that you want yours known, otherwise you wouldn't have posted anything. You don't need to come in here and try to act like you don't care because it's a lie; if you truly didn't care you would've ignored the thread.
People are here at MacRumors forum to discuss their various Apple products and their preferences. You came to the MacRumors Forum, then to the iPad forum, then to this thread specifically, just to say you don't care? Just like the groceries and PB example, doesn't that seem like a reach and honestly kind of ridiculous?
Why is it any different? Because we can find comfort in being able to be rude from behind our keyboards and computer monitors? Let's try to show a little civility towards one another by adding constructively to a person's thread.
Back on topic, I still think the iPad Air is worthwhile. It's a fantastic stop-gap between my 5" phone screen and my 15" rMBP. Not quite as portable as the phone, but most certainly more portable than my rMBP.
