An actual DOS machine gives full compatibility, which is a nice thing.[/b]

That's true, but not entirely. Some games require more "conventional" memory (a term from the Dos times) than others, some are even hard to get to run without advanced "meddling" with Ms-Dos' options, and you'll need to mess around with your autoexec.bat and config.sys files to press out that little bit more of conventional memory that's needed, which is anything other than simple if you have no idea of Ms-Dos.
So in a way DosBox is quite simplier to use than Dos, you just need to edit the file dosbox.conf, set there anything DosBox has to offer as you like it, and use few simple commands to get a game to run. The downsides are that you need a pretty fast PC for it to run the more complex games, and that not all games are supported or they run only partially good.
