Microsoft formally changed SkyDrive to OneDrive. I've checked my personal account, it is now called OneDrive. And I received emails from Microsoft confirming the changed.
"Welcome to OneDrive, the one place to store and share your photos, videos, documents and other files-anywhere, on any device, free. Over the next few months, you may continue to see both SkyDrive and OneDrive throughout your experience, but don't worry! You'll still be able to access all of your files during the transition. OneDrive is everything you love about SkyDrive and more.
One place for all your photos and videos
Automatically capture and store your favorite photos and videos from your phone so you can get them from all your devices and easily share the ones you want.
