Agreed. This is the same conclusion I reached when I started this thread months ago.
While AT&T is happy to go along with the "share everything (but many of you will pay more for less)" mantra that VZW introduced, Sprint is keeping their Unlimited plan (and acknowledges that has had a positive effect on their bottom line), and it now looks like TMobile is bringing their Unlimited plans
back.
Everyone in my family has new devices and we are all on this promo package. I hope that the cellular industry continues this swing back towards unlimited data over the next couple of years.
