Usually, the same people that are worried about going over 5gb of data in a month....are the same ones illegally tethering in the first place, lol. Because 5gb is A TON of data to use on a cell phone.
A ton of data to some, is alittle data to others. Do i listen to music on my phone, yes.. do i watch HD youtube videos on my phones... yes... do i download apps and install updates on all the apps.. yes...
As stated in one of the 4g threads, it took only 32 minutes to go over 5GB of data usage. Doing all the things you can do with smartphones, and actually doing them, takes a bit of data. Not everyone got a smartphone for the same reasons, and i'm sure there are alot of people that got smartphones just because it's the IN thing to do.
And with the addition of hulu and netflix for 4g... i will use those to, why.. because when i'm on the go i will watch a movie. I use my phone with all the capabilities it has to offer.
