I just changed my notebook over from an Acer Aspire with Windows 7 to a Mac Book Air. My applications have remained as constant as they can jumping platforms and my usage is fairly comparable. When I connect to a MiFi with the Mac I blow through my data caps in no time flat and didn't have that problem with the Acer. I did so the other day sitting through a seminar just checking email and doing very light (no video, sound, or flash surfing.

I'm wondering whether it is the way that the Mac Air's Mail is polling my Exchange email server and and wondering if anyone else is running into that. I went through over 2 gigs of data in six hours. On my Windows box, this would have barely moved the needle.
