Should they supply costs for each town in the US? It varies with not only location, carrier, but what specials are underway at the time. Dang them for their incomplete reviews.
This is something that has been really irritating me when I read the reviews here. Anyone who owns a smartphone or PDA phone knows that the initial cost of the cell phone is peanuts compared to the actual monthly costs of operating the phone. All the major phone carriers charge what I consider excessive data charges. Most "unlimited" plans charge roughly 40 dollars a month, which would double most people's monthly fee. Over a two year contract that works out to almost a 1000 bucks.
So when analyzing a PDA-type phone, the first thing I ask is "does it have WiFi?" Without this function you are basically consigning yourself to either those monthly data charges or using your PDA phone as a regular cell phone. Granted you do not have the flexibility of using your device anywhere, but you also don't have to shell out 40 dollars a month extra. The choice is up to you, as it should be.
I recently left one cell phone carrier for another because they refused to offer PDA-style phones with WiFi. I have no proof they purposefully stripped the function, but it's pretty odd how only one PDA phone by an obscure manufacturer is WiFi-enabled while similar product lines by other carriers have the option of WiFi.
To sum this up, I can't think how a product review can be complete where the actual costs of running a phone as reviewed is not discussed.
