VZW is very fair with their pricing imo. I know there are other companies such as Sprint offering special packages for their plans, but their missing quality (cell reception, call quality, etc.), at least from what I've seen with my friends on that network.
As for tethering, I am guilty of being rooted primarily to tether. I don't tether nearly as much as some of the users on this board, but the point is I have it. If somehow VZW manages to block tethering, it wouldn't be a huge loss to me. I understand that many feel we should be allowed to tether for free and as do I, hence the rooting of my phone, but really we're going behind VZWs back and pretty much taking advantage of what we initially signed up for. I do believe VZW has a right to block tethering, but I also feel we are being cheated by having to pay more for the same data just for a different use.
I will not be switching from VZW unless I absolutely need to. I've been more than happier with their service and I am quite happy that I switched over from AT&T, and I was with AT&T for a good 10yrs if not more. Not to mention the fact that VZW still has unlimited data, that's a huge reason as to why I stay with them.
