I still don't understand the "faster LTE will make you use more data" argument.
If I have 5 emails they'll just load faster on LTE but they won't use any more data.
Having LTE won't make me suddenly have 6 e-mails. Having LTE won't make me suddenly decide to watch higher-quality Netflix. (I'm fine with what it looks like now.) Having LTE won't allow me to read articles faster.
I suppose now I'll have time to read 11 articles on the train now instead of 10 but, wow, that's a whole extra page of text. I don't think that's gonna kill me.
Really, I don't see where all this new magical data usage is supposed to be coming from. Mostly, I feel like I'll just be getting tasks done quicker and putting the phone back in my pocket sooner.
What's not to like?
BUT, if your emails load faster, you can respond faster, and get more new emails faster... its a viscous cycle that will never end... and your data usage average of 1.2 GB per month will increase to 1.23 GB (random number)... BE CAREFUL of LTE
