The table of equivalents / replacements / analogs of Windows software in Linux

One of the biggest difficulties in migrating from Windows to Linux is the lack of knowledge about comparable software. Newbies usually search for Linux analogs of Windows software, and advanced Linux-users cannot answer their questions since they often don't know too much about Windows :). This list of Linux equivalents / replacements / analogs of Windows software is based on our own experience and on the information obtained from the visitors of this page (thanks!).

This table is not static since new application names can be added to both left and the right sides. Also, the right column for a particular class of applications may not be filled immediately. In future, we plan to migrate this table to the PHP/MySQL engine, so visitors could add the program themselves, vote for analogs, add comments, etc.
