Here's a good but brief review of FreeDOS over at OSNews.com. The take away, DOS is not dead! And for all you PC/GEOS, NewDeal Office and Breadbox Ensemble users, know that these versions of PC/GEOS run on FreeDOS as well. Since publication of this review note that FreeDOS has reached the 1.0 production ready version of the software. Also, if you decide to install FreeDOS, take a few moments to investigate the GEM graphical user interface and the Seal graphical user interface. I think you'll agree that PC/GEOS blows either of these GUIs away!
