Microsoft has been leveraging their SkyDrive brand more often lately.
The recently announced free cloud based version of Microsoft Office 2010 is located within SkyDrive.
Those who downloaded the new Live Essentials beta last week not only noticed Office 2010 - like 'ribbons' and a significantly improved suite of free add-ons to Windows 7, but also may have noticed interaction with SkyDrive.
Now, Microsoft's Office Live Workspace is becoming part of Windows Live SkyDrive.
Some information on the Office Live Workspace upgrade is now available here.
