Microsoft has announced an update to their popular cloud storage system SkyDrive (part of the Microsoft Live.com family of free cloud services). With this update SkyDrive will essentially be part of the Windows 8 metro style interface. There will also be integration to allow access to your SkyDrive from the Windows Explorer window in Windows 8. This will make it as easy to access your SkyDrive as is your My Documents folder.
