I will agree completely with the last line there as a minimum, but will also mostly agree with the rest. Where I don't necessarily agree is that people who watch video on their phones are going to opt for 720P or 480P video when they have available 1080P or higher. It's only natural to want to start with the highest quality image and audio, given that what you watch and listen it to will often bring the quality down.Look at the numbers....Sure, they CAN do that with the highest quality video, but in fact you can't see that on a tiny cellphone. On a practical setting, 100GB is 300+ hours of video a month. And longhaul truckers might have half that time available on the road if they were watching video on their cellphone 8 hours a day.
Maybe they can "easily" use 100GB...they can just as easily use a lot less.
Yes, self-control is a big part of this, moderation is the key. Still, they have what they at least perceive is a "unlimited data plan", and so like almost anything (except elephants, apparently), if you take a leash off it, it will roam out farther and farther as it realizes the leash is no longer there.
