I have been requested by many to reinvent the wheel of links to the best office productivity suites. My favourite links are:
LibreOffice: http://www.libreoffice.org by the Document Foundation
CalligraSuite: http://www.calligra-suite.org by KDE based on Qt
OpenOffice.Org http://www.openoffice.org by Oracle
These are the most mature Desktop suites with equal or better offers than MS Office Suite.
On the web, the most robust one is ZOHO: http://www.zoho.com. Also you have GOOGLE DOCS which you get by default in your gmail account. However, it leaves lot more wanting.
On mobile platform, there are several prototypes. I have yet to come across a good one. That's one reason I am not buying any Tablets. There are some readers for android too! However, do not get fooled by names such as Quick Office etc. They do not support ODF.
