>Aside from just ancient proprietary shit, does it have any good software?
Much of the "ancient proprietary shit" was actually pretty good, like early MS works, Borland C, WordStar, etc. If you want to go the free route that's out of the question though.
GEM is the best free GUI, not sure about 32-bit support or UTF-8.
There's TELNET and FTP clients/servers, and web servers if you're on an 8088. If you've got a 286 or better there's SSH and web browsers.
In all honesty though, if you're using something old enough for DOS to be a contemporary system, you might as well run Minix or an early Debian/Slackware with DOSEMU. 386 and higher isn't really utilized by DOS. Even an 8088 will run XENIX, Minix, or ELKS, but you'd probably want to dual-boot as there's much less software than for DOS.
I run FreeDOS on a 286 and it's pretty comfy as an office and C/QuickBASIC machine. It's sluggish on earlier hardware though, probably because there's much more C than ASM compared to MS-DOS.
