This topic always pics my interest as DW and I have a grandfathered plan with Verizon.  We don't download movies or music and we run ~15 megs a month.  I would suggest to anyone who is looking for a less expensive data rate to shop around as the old song goes.  Depending where you are, and we have traveled extensively from coast to coast and into Canada (that's a pricey place for phone service we found out) there may not be a one size fits all plan.
