Edit: I forgot to mention the no fee for tethering or hotspot. I use that enough for it to be very helpful but not to pay an additional fee.
Here comes added congestion from iphone users. Here comes a price increase (customers end up paying for most mergers in the end), etc. Hopefully by the time the deal goes through Verizon will have a full LTE roll-out and decent Android-based phones to take advantage of it.
I'm a little surprised this move is going to even take place. In markets with only a few providers, cell phone prices and caps are terrible. Take Canada for an example. Now the US will follow in Canada's footsteps.
I think the industry is set on killing competitive pricing. The dream of the mobile providers is to convince everyone that a $100-$150 monthly bill with 2+ year lock-ins is normal. Mobile data should be a commodity, not a premium service.
