I’m not particularly fond of Microsoft’s Office and don’t resort to it for personal use. I have been shifting most of my documents and files onto Internet applications, such as Google documents and haven’t been disappointed so far.
They big advantage here is accessibility. While there are lots of ways to make your Word and Excel files shareable, you don’t get any hassle from Google Doc’s and the tight integration of all Google products make it easy to manage files.
I simply love it and I believe online offices are the way to go in terms of productivity!
