Not really. The new plans more or less average out to being the same as before. Higher data users will pay more, lower data users will pay less. The only reason tech blogs uproar about higher costs is because most tech blog visitors are on the higher end of the spectrum.
For my family, the new pricing is exactly the same, but we had two tethering plans, both of which we no longer need. We actually will save $60/month once we go ahead and move over to Share Everything. (Haven't done it yet, it's on the to-do list.) Other people who have complained about the new pricing, thought it was horrible, till I pointed out they would pay exactly what they're paying now. People putting 15 GB on 4G are going to be paying more, but that's because they shouldn't have been burning 15 GB on 4G in the first place, IMHO.
