This is fine with me and 90 percent of people. My bill is going to drop by 15 bucks per month. I have been looking at my usage and only twice in the past year have I gone over the 200mb limit that will be offered. Thats great. If I monitor usage more I can make sure that my bill drops from 80 to 65 a month and not really have to change my habits much. I think most people are the same. And if you are using over 2 gig per month, then WOW! I know heavy users that never cross 1 gig. And even at the 2 gig limit, its still 5 dollars cheaper every month.
Sure this will hurt people that like to tether but I'm a geek and have never tethered anything. I just don't need to. And the average consumer won't either. There are some hardcore geeks out there that will be up in arms over this but oh well. The rest of us are going to enjoy that extra 5 or 15 dollars per month.
