S4 offers a lot of new stuff that I can see. IR Blaster, Smart Pause, built-in pedometer, etc. It will be a worthy upgrade to the dual-core phone owners of two generations ago (and maybe new smartphone / iOS owners), maybe not so much for current S4 owners.
There's also the other side of the coin - herd mentality. During your 'study', does the average Joe demonstrate a strong sense of independent decision-making (I will not buy S4), or does he go with the flow (I bought S3 becos everybody had one)?
I suspect a lot of people had individual opinions in the beginning but eventually succumbs to
perceived societal and peer pressure in order to blend in. Public acceptance is so important these days, especially to the younger crowd (Gen Y and younger).
Ah Latin. The only Latin I know is 'carpe diem et memento mori'. Luckily there's Google

That's true, but the fear of rejection by peers make some people accept whatever others are preaching. Is there Latin phrase for that?

So would the hive mind be a good thing considering the phenomenon of herd mentality? We still need to judge for ourselves. Nice discussion.
