- The main difference is that microsoft is so much expensive and libre/open office are free.
- LibreOffice and Open Office are compatible with a lot more systems, including Windows, OS X, and Linux, while Microsoft Office is restricted to just Windows and Mac OS X..
- OpenOffice and Libre Office can handle more formats than Microsoft Office.
- You need a more potent (not so much) PC to run Microsoft Office.
- Microsoft Office requires much more space in the internal disk.
- For every copy of Microsoft Office you can install it in another three PC´s, but Open Office and Libre Office instlations are unlimitated.
