but are there really "many" that use 2GB+ legitimately or not? the numbers would disagree with you. if 95% use less then 600MB and 99% use less then 5GB, I think it's a safe assumption that not many people use 2GB a month. It does suck for those like you that do, but again, you are the one in the minority (and a very very small minority at that)...
With Android known to be a data-intensive operating system, it is easy to use up 2 GB legitimately. All you have to do is rely on the cellular network totally and not use WiFi. And I would think that the vast majority of smartphone users (which would greatly outnumber us that frequent forums like this) most likely DON'T use WiFi and DO use the cellular network.
Here is the data usage from my 5 lines, all on Android phones, for the past 3 months, chronologically in reverse (most recent month first), with 99.9% of the data usage being on the cellular network.
Line 1 (Thunderbolt) - 770 MB, 2033 MB, 1473 MB
Line 2 (Thunderbolt) - 819 MB, 1065 MB, 634 MB
Line 3 (Droid 1) - 220 MB, 427 MB, 505 MB
Line 4 (Droid Incredible) - 1575 MB, 1987 MB, 1172 MB
Line 5 (Droid Incredible) - 362 MB, 537 MB, 757 MB
I only included three months because prior to that lines 3-5 were not Android phones. Two were Blackberries and one was a feature phone. Also, these three months were full months with the Droids on them. A few things I have noticed analyzing my lines:
1. Line 1 is mine and prior to the Thunderbolt I was using the Droid 1. For those months when I was using the Droid 1, my data usage typically ran around 300-500 MB per month. My usage habits really haven't changed much, except for downloading interesting free apps for the day from the Amazon App store so I am downloading a bit more than before, and with the Thunderbolt, Verizon's Backup Assistant is set to sync (this is not available in the Droid 1). That 2 GB month also included the Thunderbolt update (which I downloaded off the cellular network) and with the rebooting issue, required me to do a factory reset which meant that all my apps had to be re-downloaded.
2. Line 2 is my wife's. Prior to these three months she had a string of several months (when she was on a Droid 2, before it was stolen and I replaced it with the Thunderbolt) where she was streaming a lot of Asian soap operas using the browser and Adobe Flash. Those months she was averaging between 8-9 GB per month.
3. Line 4 is my daughter's. She doesn't stream music or Netflix, but she Twitters and uses Facebook a lot.
And I would suspect, with stuff like Netflix and cloud storage becoming vogue and encouraging people to use more data, average data use will go up.
