Listen to Mickey (the Cell Phone Junkie and frequent guest on A.C.). Find the carrier that provides coverage for 90% of your time. For those of you able to go with T-Mo there is no doubt that it will be cheaper BUT there are MANY of us outside of big cities (T-Mo only covers about 220 million Pops (as Mickey calls them) of the total US population). Verizon has 450 markets covering almost 300 million pops with the stated goal of covering their current 3G areas by the end of 2013. Although not traveling as much lately (I used to be on the road 150 - 180 days a year) Verizon does have a better network - if someone else is better and cheaper, good for you, otherwise you need to check out the other carriers (whether it be T-Mo, Straight Talk (ATT or T-Mo), Sprint, or even one of the regional carriers. I would have to KNOW that another carrier provides better coverage everywhere I travel (mostly US, mostly urban) before I could justify switching from Verizon because I can't stand surprises and I need to be able to be reached and call home when I'm on the road. While there may be a FEW places where another carrier is better than Verizon, there aren't many and while I would love to have an alternative to Verizon, right now there isn't one. By the way, one place where Verizon shines is at high density events like sports stadiums and CES.
