"The Windows Mobile Business Value Calculator gives you immediate visibility into the impact of deploying mobile business solutions on the Windows Mobile platform. Using a company's unique information, such as number of mobile workers or types of applications to be mobilized, and summary data from IDC, the Business Value Calculator allows you to quantify the benefits and the direct and indirect costs of deploying mobile line-of-business applications, including measurable impact on revenue and income, operating expense savings, productivity enhancements, and other strategic business improvements. The resulting value metrics will help you build the business case for choosing Windows Mobile as the standard platform across your organization." 
Microsoft has released a Business Value calculator to help customers determine the true savings that they could see by switching to a Windows Mobile solution for their mobile workforce.

However, if you're running a different mobile solution, and you're contract is coming up for renewal, this tool will help you make the right choice.
