Bill Gates' Web Site - Speech Transcript, Microsoft Mobile & Embedded Devices Developer Conference 2005: "As you use these different devices, we think about the user and we think about how you collaborate with other users. For example, the idea of not fragmenting communications, over time even the idea of the phone number will be fairly obsolete. You will just think of using that e-mail address for all the things you do, whether it's SMS, instant messaging, dialing, starting a videoconference, and in some cases you'll simply use a picture-driven interface where you don't need a name at all, you just pick the picture and then pick exactly how you want to communicate.
And so communications are coming together across these different platforms, even to the point where you ought to be able to walk in with a phone conversation taking place and transfer that onto, say, the PC and have a full screen sharing experience without rebuilding that connection. Having your contacts shared, your group name shared, not thinking of buddy lists as being separate from what you're doing with e-mail, that integration can simplify communications.
We believe in collaboration, letting you take things like photos, the business data and share that in what we call the SharePoint facility. That information you should be able to connect to from a mobile phone and be notified of things that are important, things that you care about."
