WK 8 exc Online application of tools

Thought this was a great site, because anyone can access and use word documents and spreadsheets without having to download software. The major thing being it's free. You can also access word documents whenever you have internet access, and you don't have to worry about having a compatable computer when using or sending data. I can see why this could have an impact on Microsoft Office as far as people buying their software. I can see the positive side for multiple users being able to edit files, but I also think this could have a negative aspect aswell.
