Microsoft has an estimated 100 million users of its SkyDrive “anywhere access and sharing” service today.

According to Brian Hall, General Manager of Internet Explorer and Windows Live, “We need to turn SkyDrive into a destination application,” while keeping the underlying Skydrive infrastructure,

He cited as an example a SkyDrive application for the phone that would allow a user to see all information — files, photos, Office Web Apps documents — that they stored in their 25 GB of free cloud storage available with SkyDrive.

Microsoft is developing  a new HTML5 based version of SkDrive. SkyDrive also may become a place to store music, as well, as LiveSide has noted.

Hall described SkyDrive as part of the “communications properties” under the Windows Live brand. The other two, according to his definition, are Hotmail and Messenger. SkyDrive allows users to “store, organize, and download your files, photos, and favorites on Windows Live servers, and access them from any computer with an Internet connection,” as Microsoft explains on its Web site.
