Pros
Pro Use old editor Edit
The grandfather of Notepad, very easy to use, hassle-free text editor.
Pro Brings back memories to older developers
Pro Best OS to run QBASIC on
While QBASIC works on newer operating systems, such as Windows 95 and Windows 98, it was designed for and runs best on MS-DOS.
Pro Open Source
GNU GPL
Pro Large and friendly community
You won't be let alone, any question submitted on FreeDOS forums will be detailedly answered in a few hours time.
Pro Compatible with MS-DOS apps
Pro Supports FAT32 partition
As opposite to every MS-DOS version equal or older than 6.22, or any DR-DOS version, you won't be restricted by a 2 Gb large FAT16 partition.
Pro Highly portable OS
It takes ten minutes to make a portable, USB FreeDOS drive, All you need is a USB device FAT or FAT32 formatted (128 Mb should be enough, but a 2 GB device would be better). First make a FreeDOS bootable USB drive with a program like Rufus (on Windows) or UnetBootin (on linux or Mac). Select it at boot and run fdisk to make a Primary DOS partition and install FreeDOS on it. Final step: reboot and run fdisk again to make the new partition active (optional: delete the installer partition). After that, the system is ready to boot with any computer.
Pro Extremely lightweight
Takes less than 10 seconds to boot.
Pro Easy to dual-boot, either with any Linux distro or Windows
If you install a Linux distro after Freedos, GRUB2 will automatically detect it. As for Windows, newer EasyBCD releases implemented FreeDOS and automatically recognize it.
Cons
Con Not a modern OS
If you need to know how to run legacy software that will run on DOS (crazier things have happened, there's probably still some ancient, leviathan, software out there that requires it), go for it. Otherwise you're practicing skills that are out of date and are using an operating system that is woefully insecure.
Con Literally horrible
MS-DOS is terrible -- just read about real mode. It was an almost decent solution for its time, but not anymore.
Con Way too simple
A stripped down version of Unix, some commands just got renamed and advanced options removed.
Con Dead
Ended in the 21st century.
Con No internet support
Using Internet with MS-DOS is not trivial.
Con Unlikely going to be your PC main OS
If looking for a lightweight OS, and thinking of FreeDOS as a possible option, consider that it will only useful when having to deal with legacy software, or other dos-based programs still commonly used at workplaces. Nonetheless it's a fantastic solution for Retro-Gamers who still own a a supported sound card. However the lack of modern software makes it hard to accomplish common everyday tasks, such us opening a document written in UTF-8, not mentioning, obviously docx and pdf files. The best choice is to install it on a USB drive, in order to have a portable OS, with basic hardware and all your files (and if you want games) ready to be launched with every machine. Useful to edit partitions, as well as restore MBR, check errors, install a light bootmanager on any kind of FAT partiton of every IDE-mode compatible hard-disk.
Con Obvious lack of sound card drivers
If you own a sound card produced after than 2000, you won't find a driver to make it work.
