Cloud storage war has getting increasingly exciting. Microsoft has updates its own online storage “SkyDrive” and make it available in almost any Operating System. It supports  Pc ,Mac, Windows Phone and IOS. Sadly there is no official android apps yet but Microsoft is kind enough to recommend some third-party apps.


Microsoft has allow live mail users to have 7GB of storage.However, if you are long time live mail(or hotmail) user, Microsoft has give a free  generous upgrade to 25GB of online storage in a limited period. This is by far the largest amount of free online storage. This will post a lot of threat to the famous Dropbox which only give 2GB free storage and the enterprise focus Box which has 5GB free online storage.
