Many of my friends already know this, but I am a fan of open source. I haven’t gone as far to live my life Microsoft free (mainly because I have never gotten the hang of Linux), but most of my work is done on free and open source software. Art, office documents and even this website all run open source software.
Being a Windows user, this sort of software was hard to find since most of it was only available on open source platforms like Linux. In recent years though, more and more of the software has been written multiplatform. Most popular applications work on almost any current system including Windows and Mac OS X. A lot of them even open popular file formats like office documents and Photoshop files.
