Over the Summer, Microsoft increased the quota for individual GT OneDrive for Business accounts from 25GB to 1TB.  That's right...each account has access to 1TB of cloud storage.  You can find more information about OneDrive for Business on the OIT FAQ web site.   UPDATE: According to the Microsoft Community site, the Mac OS X version of OneDrive for Business is in Alpha stages as of August 2014.   Office for Mac 2014 will be out later this year and it's possible that it will all come out together, but nothing has been announced yet.
