QNX Neutrino 6.2.0 had a good web browser, file manager, editor, terminal (shell) program and other basics needed to create a usable desktop environment for a premium development system. It also had some bells and whistles of its own for creating the desktop look and feel the developer desired. What it lacked was user programs such as paint programs, spreadsheet programs, word processing, games, stuff like that. Some programs were made available by others for download from certain repository sites. I downloaded a few games, a version of Opera which provided some enhancements for the QNX Voyager WebBrowser, a version of Mozilla and an email program.
In other words, the basic system was usable right out of the box and I could surf the net right away after installing the system. But a casual user like me had to go out and find the other programs that I wanted to use.
I haven't tried QNX 6.4 yet, so not sure what it has available.
