Google is bringing the popular concept of an app store to its Google Apps suite of online productivity software. Third party developers will be able create their own software that will integrate with the core Google Apps products. One example comes from Intuit, maker of payroll and accounting software. An interesting feature of its software is the ability of an employee to get pay stubs by simply going to their calendar. Another developer is integrating support for Gmail, calendar, and chat into its software. By having all the applications in one window, it should be able to increase productivity. This move is aimed towards business customers, and is unknown how it will affect the average internet user.
