I've been thinking of making the switch to T-Mobile myself...their new plans and policies just seem a like breath of fresh air compared to AT&T or VZW...it's just too bad they don't have the same coverage.
Yeah, we actually even left AT&T when all the "Unlimited" throttling thing broke, and went over to Sprint to reward them with our business for them being the only ones still giving what everybody knows nearly all customers want (Unlimited). But unfortunately, their service was just too bad to stay, so we went back to the grandfathered plan.
From reading articles about how the U.S. (the richest country on earth) is actually behind the quality / speed of data in European countries, to articles about electric / utilities companies not updating and letting their infrastructure crumble while continue to charge as if they were, it doesn't seem like there are a lot of wise decisions being made. Like you say, better policies will definitely be some fresh air.
