By signing up for a Google account, one can have access to Google Docs, an online word processor and spreadsheet developer. Why use these? The files can then be shared with anyone, and they are always available online. Suppose you are working on a report, and you need some help. With Google Docs, you can share the document with a friend and get his/her opinion.
Now Google is offering a free presentation tool that works very much like PowerPoint. Again, the presentation will always be available to you online and can be shared. This is a nice alternative if you do not have PowerPoint. To read the article from MSNBC, click http://www.msnbc.msn.com/id/20829609/.
