It's narrow-minded to think that there's only two categories: people with "enough" data or the ones who shouldn't use a smartphone at all because they don't have/need/want more data.
Every prior iteration of iOS was able to keep data usage to a minimum. With iOS 7, it suddenly escalated. For most people, 300MB of data is still enough to do whatever they want.
I think that's pretty interesting to actually see what other people do with their phone, in particular their data usage. Would you be so kind to post your usage?
I'd like to see a reason to justify large amounts of data that's needed to operate the phone.
I can see that apps exist that need to use data, i.e. video streaming ( Youtube, Netflix), music streaming (Spotify, Pandora, iTunes Radio/Match), image sharing ( Facebook, iCloud Photostreams ). But the necessity of these is highly, hmm, say, subjective
Not all people use their phone like you do, keep that in mind. Not all need data hungry apps or use them at all. That's my point. And these got cut off by Apple. Maybe they hope that prices are going down and get evened out.
