I paid full retail when the Razr came out in Nov as a pre-emptive strike against such a move, so I'm not thrilled about any changes to unlimited data. That said, I'm going to keep my powder dry and will wait for an official announcement, especially to see exactly how this will affect those of us who already have unlimited 4G plans.
On another note, I keep reading about how some of you plan to jump to Sprint. VZW could care less - they will keep rolling in the $$$ with or without you. The vast majority of the population doesn't care about this. It's mainly those of us who are 'gadget geeks' who care and we are a very very small percentage of VZW's customer base. My prediction is that very few who talk about jumping to Sprint will actually do it, and many of those who do will come back eventually due to poor coverage and/or extremely slow data. VZW knows this - they aren't stupid.
Bottom line, it sucks, but it is what it is. Welcome to 2012.
