PC World: "Google is firing up a Google Apps campaign to try to convince small and medium businesses in four metropolitan areas (New York, San Francisco, Boston, and Chicago) to "go Google". They've set up a special site called "Apps At Work" for the campaign.
Most people have used Gmail so they have an idea of what Google Apps is all about (which is great for migrations). Google Apps offers a clean, web version of what Microsoft Exchange and Lotus Notes offer but at a fraction of the cost. For those who love Outlook, Google has made Apps look like an Exchange Server behind the scenes so that users can stick with Outlook until they become comfortable with the web interface. "
