Microsoft now offer all the familiar Office suite Apps as Online versions now, including Word, Excel and PowerPoint. Using these Apps in their online form means all you need is a device with a Web Browser to edit documents online without having to install the desktop versions although this is still available.
New collaboration features now available with these Apps include the ability to share a document with colleagues which eliminates the problems associated with emailing a document to colleagues for comment and receiving multiple copies back. There is one master document where all comments and changes are collated automatically! This feature comes into its own when combined with the co-authoring function which allows multiple users to edit the same document at the same time - in real time!
