I think you're about right. I recall reading 40 somewhere (preferred).
200 for preferred is probably close enough to "enough" that most won't ever touch that. It's also the tier that "most" are on.
When I was checking things about a year ago, I recall seeing a few months of pretty high usage, but far less than 200GB.
With this news I feel much better about not worrying that I'd hit some cap. Granted, I suppose I could get there and even surpass it, but thankfully they are still "soft" and would only hassle me if really needed.
That, and I'm in a college town. Tons of folks likely use a LOT more bandwidth than I would
Nice to hear about the updated policy. Glad they went with some fairly fair numbers instead of some insanely low one like AT&T wants to with DSL.
