Las Vegas has been called “America’s Playground” by the movie Ocean’s 11. Now that Clearwire is preparing to launch WiMAX in the casino city, I’d call it a “nerd’s playground.” The image above proves that Clearwire is getting ready to introduce WiMAX service into the city, but there won’t be an official launch date announced until later this summer. Other cities that will be getting WiMAX soon includes Atlanta, Georgia and Grand Rapids, Michigan.
