That's not how the 3G data plans work on the iPad.
Ok...well then tell us how they work and how they compare to my statement(s). Don't just make broad claims of how things supposedly work.
And you get warnings at certain % that you are getting close to your data limit.
Nice fear mongering though.
1)How does one get the warning? email? popup on the device?
2)I'd be willing to bet, after seeing how many kids (and adults) ignore warnings and popup boxes and just click OK, that a LOT of people using a Touch's 3G service will go over, and get raked over the coals for usage. I'm sure the end user will learn their lesson after 1 or 2 times, but I'll bet you my house that a high percentage of folks will somehow not see (or care) about the 3G usage and keep on streaming their 6MB songs and their 30MB Youtube vids and downloading their 4MB games and sending emails with 3MB attachments until they get the bill. If I were to get the 3G service, I would sign up for something in the gigabyte range/month or unlimited/month.
