These are the common apps that you use on a computer such as a word processor, spreadsheets, and presentations.  Most of us are familiar with and use the Microsoft Office suite of tools for this purpose. However, Web2.0 brings us a number of online alternatives.  Imagine have all of your documents, presentations, and spreadsheets available to you on any computer...no expensive software to download or install.  Now, add the social component of Web2.0 and you can share and co-edit documents.  Let's see...which is better???
