“First to mind when asked what ‘the cloud’ is, a majority respond it’s either an actual cloud, the sky, or something related to weather.” - Citrix Cloud Survey Guide (August 2012)
Do you use DropBox or similar to synch your work? Do you share documents with your colleagues using online services like Google Drive (was Google Docs), SkyDrive, Office365, and others which are outside the University?
