We all know the de facto internet filesharing and cloud storage tool until now has been Dropbox, but Microsoft has always had their own offering, SkyDrive. SkyDrive gave you 25GB of storage for free, which is a good deal more than Dropbox's measly 3GB. Problem was, SkyDrive was not really available on anything else than Windows (and Mac), and there was no mobile integration except with Windows Phone 7. Now Microsoft is starting to put SkyDrive into the devices people use every day, instead of only giving it to the Windows faithful.
