Wireless prices in the USA are higher than any other country I've been to, developed or not. Nevermind the absurd contracts.
In Taiwan, for example, I got a 3G phone plan for $40 month-to-month, unlimited data, and consistently ~20mbps download speeds.
In developing countries like Thailand or Central America, I can get a 3G card for 60 days and 1-2GB for less than $10. Speeds obviously aren't as good as Taiwan, but the basic access to Internet is way cheaper.
