I think very few people who say they need LTE actually truly do need it. In a matter of five years (or less for some) people have become attached at the hip to their smartphones. The fact that LTE will make your work marginally faster likely doesn't mean you need the speed. Let's get real people.

View the other side of the coin here... there would be absolutely no refining if somebody didn't adopt the first gen chip.
FWIW most of the disappointment comes from the elongated screen. In fact, most of the concern (that I am seeing) is basically that people feel this IS change for the sake of change. You stretched the screen. Whoopee! Pretty much the definition of change for the sake of change, unless of course we get some killer feature that nobody is really anticipating.
Not necessarily true about the "no refining if no one adopted the first gen chip", because usually if a manufacturer can make their product more energy-efficient, smaller, and work better overall, they will do it, whether or not the first gen chip was widely adopted. This could just be speculation, but I'm basing it on the fact that those same manufacturers also know that until a certain product meets certain requirements by mobile device manufacturers, their product will not get widely adopted. This applies to Apple because they have strict power requirements for their mobile devices and one of their top priorities is battery life on their mobile devices, and since Apple usually orders tens of millions of certain parts for the iPhones they plan on selling, they are a potential huge money maker for manufacturers who make different mobile device parts like LTE chipsets.
Also, one subject of LTE speeds, it's not necessarily the fact that people need the speeds, it's just that consumers will want a device that uses the faster speeds to get their work done faster.
P.S. Sorry for any spelling/grammatical errors. I quickly typed this out on my iPhone waiting in line at an amusement park lol.
