I decided to do some math after being surprised to find 3 days worth of data usage appearing abnormally high on my iPad. Attached is a pdf detailing a quick check I ran on the cumulative size the front page of sites I frequent plus a couple of other popular ones I don't (Dark Secret: I'm not really into twitter). I also included AT&T's front page for good measure. It's a list of 15 websites, and if I visited each three times a day making sure to only visit the home page and click no links as well as making sure I didn't use my 3G data plan for anything other than this I would be about 10 megs short of the 2 gig cap. Apparently AT&T thinks that "browsing the web" on an iPad for the average user almost exclusively entails text only websites. Another reason I put this together is to illustrate that "heavy" users aren't necessarily people guzzling down streaming video haphazardly robbing innocent users of bandwidth. Simply browsing the web is enough to place you in that group as well. Not that I necessarily think > 2 Gb a month means you're a "heavy" user, but this isn't really about what I think.
