I'm on this a lot of the time, Amber. Between CrackBerry time, google time, e-mailing, BBM and all that I do, plus navigation and search time, I use a lot of data. Last month was one of my busiest, 1.47 GB used. My wife and daughter combined usually don't break 60MB.
I also use a lot of images in various things.

Wow, I thought I was a heavy user, but you guys blow me away.
Mine usually runs from 40-130 MB per month. I use my BB all the time, but I don't do any streaming, podcasting, or other such things, so I guess that's why.
