WSJ.com - Microsoft Wants Your Office Telephone: "The founding vision for Microsoft Corp. was a computer on every desk, each one running Microsoft software. The next dream is every office phone.
Today Microsoft is set to announce a broad initiative into the business telephone market, including desktop phones and videoconferencing devices designed by Microsoft and sold by partners, with some available as soon as June 2007. Microsoft software programs would link the new phones to computers so that they can handle voice functions, such as making a phone call and receiving voice mail."
Deja vu, in some respects; see, e.g., this NYT article from five years ago.
