"We see the mobile email market as really poised for explosive growth. It's really a small market today and we feel the reason for that is a lot of the solutions that have been out there are first generation solutions that are really expensive. They're pretty complex. And our strategy is just to make mobile email part of the mail server and to enable a broad range of devices. So what you see us doing is, we have a technology we call Direct Push…it's part of Windows Mobile and our Exchange Server as well as our small business server product. And any customer that buys Exchange Server or our small business server, they get mobile email for free. In addition to mobile email, they get to choose from a large number of devices. We have over a hundred phone designs today. And in addition to that, they get all the benefits of having the Windows Mobile software platform…music, TV, Office Mobile. We really feel that mobile email is just a big, big market." Beyond email for business users, Horn says Microsoft is working on bringing its Hotmail, Web based email service to a broad range of cell phones. Bloomberg Boot Camp, I'm Fred Fishkin.
