This 'internet' thing seems like it could be popular one day.
Have you ever heard of a 'Web App'? It's like using Adobe Photoshop to add witty captions to pictures of adorable cats, but WITHOUT the actual application! You can just load up Internet Explorer and edit the image from there. The application itself is stored in a magic fantasy land so you can edit to your little hearts content from any computer. That way it's not tied down with software you need to load everywhere.
Microsoft will soon be taking the wraps off of their Office Web Apps. You will be able to edit Word Documents, Excel Spreadsheets and Powerpoint Presentations from inside of IE. I'm telling you, these intertubes are just super. Pretty soon these installation discs will go the way of the Dodo, or to a more topical extent, VHS. (And If I wanted to get really nerdy, 'HD-DVD')
Microsoft has stated the Web Versions of their popular Office Suite will be available in the first half of 2010, with beta invites coming out in August. That looks to be the year of Microsoft Vs. Google. They already have their OS battle on tap, and now will have a Web App Battle Royale. (Google already has Web Apps in place with their Google Docs suite.)
Play me off, Keyboard Cat!
