Among other applications for GEOS is GeoPublish, another WYSIWYG word processor but also combines drawing abilities.

There are also a large number of games that are designed to run inside the GEOS environment.

Uh, whoops. I was messing around doing some stuff I shouldn't and I made it crash. Apparently some types of system errors can be detected and handled in the GUI.

Finally, I found this quite interesting. This version of GEOS is bundled with an on-line communication program for a service called Quantum Link.

Quantum Link was a very popular on-line service specifically for Commodore 64 computers. Quantum Link opened in November 1985, eventually created spin off services for other platforms such as PC-Link, and eventually grew in to what we now know as America Online.

Quantum Link featured interactive chat, online games, an online store, and, of course, news.

The Commodore 64 specific Q-Link service remained popular for a long time and continued until November 1994 when it was shut down by AOL in favor of newer platforms. Many Quantum Link customers switched to the AOL service on a PC or Mac, but the AOL client was not available for the Commodore 64.
