Need some free online storage? Check out Windows Live SkyDrive (http://explore.live.com/windows-live- skydrive), which provides 25 gigabytes (GB) of storage for free and allows you to work with the online versions of Word, Excel, and PowerPoint, even if you don't have the desktop-bound counterparts.
It's even possible to map your SkyDrive to Windows Explorer so that it shows up just like a regular hard drive in Windows.
