What is very encouraging is how much great applications software is open source. That's right -- free for the asking. If, for example, you don't want Microsoft Office, OpenOffice and LibreOffice are great alternatives that are both free and can both read and write Microsoft Word, Excel and Power Point files. The Gimp has emerged as a great, free alternative to Adobe Photoshop and how many Internet sites are built on Wordpress, a free package that users upload to the server space they either own or rent?
Another great thing about open office application software is that it's pretty well platform independent. OpenOffice is available for Windows, Linux and Mac OS. Linux users with OpenOffice get the ability to read or write Microsoft Office documents and they would be unable to do that otherwise.
