Been tethering with my Moto Droid 1 for almost two years and havent been dropped yet. Usually people that get into trouble are the ones that spend all day on Netflix or something stupid like that. I keep it simple though, no heavy surfing. I tether to my laptop, nook, or ipad 1. Even though I have an unlimited plan I usually always stay under 5gb a month so I'm never red flagged and there is no way in heck that I'm going to pay $30 extra a month to use the same data I already pay for but on a larger screen
I certainly share your frustration with regard to data plans on various devices. Any you are undoubtedly correct that if your usage patterns remain consistent once you tether your iPad to a smartphone, you are unlikely to generate attention from your carrier. But those who go that route should keep a couple of points in mind. First, the TOS you signed puts the power to define "abuse" of the network completely in the hands of your carrier. They determine "abuse" and you have no recourse other than to pay an additional fee or take the carrier to court. (Hint: They have more attorneys than you do.)
Second, there is a strong likelihood that you will use more data services when you tether to an iPad or computer than by using your cell phone alone. Although you may simply replace use of one device for the other, it's more likely that you will surf more, download more streaming content, etc. when you have a device that displays the content in a more attractive and accessible manner.
Bottom line is that if you don't increase your use of the cell carrier's network significantly after tethering your iPad, you're unlikely to attract the attention of your carrier. But if you DO attract their attention, the carrier holds all the cards.
