Google Apps passes two million customers

Google (GOOG) says it now has two million customers using its Apps products. The online software offers many of the features of Microsoft (MSFT) Windows, but operates on Google's servers instead of on the user's PC.

Although the Apps client base is growing, it may not be bringing in much revenue for the search giant. According toReuters, "Those include both larger businesses that pay $50 a year per user for Apps, as well as firms with fewer than 50 employees that get the software for free."
