Using Microsoft CRM Mobile Express?

Are you or one of your customers using Microsoft CRM Mobile or Mobile Express? Do you have a unique use for it? (I have a partner out of NC doing a cool use it as a Quality Assurance tool for a cleaning company. (Which is a use I never would have expected...) ) If so, please drop me a line. We are looking for some customers to do a case study with around Mobility. Do you have one?
