Free Open Source LibreOffice 4 Review | Solo Pro World | 21st Century Business |

LibreOffice is the full-featured suite of office apps that costs nothing and runs on everything. If you don't want to pay for Microsoft Office or Apple's iWork then LibreOffice is virtually your only choice...but Apache OpenOffice is far behind LibreOffice in power and elegance. If you want to leave your documents in the cloud, Google Docs gets the job done in a highly-polished but low-featured way, but LibreOffice is the only free, open-source desktop office suite that's even worth considering.
Free. Open-source. Cross-platform office. Almost as full-featured as Microsoft Office. Can import documents in formats no other office suite can manage. Familiar menu and toolbar interface.
Some inconsistent built-in defaults. Confusing, misleading option-setting dialogs.
LibreOffice 4 is the only serious choice for a no-cost open-source desktop- or laptop-based office suite. Its interface may be a bit clunky and outdated, but it's undeniably powerful and full-featured.
