I'm thinking more and more about an Android device after my sister picked up a Hero. The only thing holding me back is the BlackBerry and its ability to compress data. I only have a 500MB plan and with my Bold I'll rack up 250ish MB per month. I'm afraid that I'll go beyond my limit with an Android or Blackberry. The one month I used an iPhone, my data usage was over 650mb.
im not sure what my data usage with my storm was since i had an unlimited plan, i also have an unlimited plan with my droid and here is this months usage.
im not sure what all the data was as i have not used any wi-fi tethering.
