What people warn about
Poor BIOS boot support on new machines · 1
FreeDOS is no good at all for booting anymore, since BIOS support is increasingly rare.
Nov 2025 · commentAwkward file transfer on modern machines · 1
Used a USB floppy drive and moved files using floppies, which seemed appropriate for a DOS laptop, but was not very convenient.

What hackers pick instead
- WindowsRecommended for running the software and games people depend on, day-to-day stability and solid underlying engineering, but critics widely object to Windows 11's ads, telemetry, forced accounts and UI regressions.1287recommend
- macOSRecommended for consistent keyboard shortcuts, strong security, tight Apple ecosystem integration and getting work done without fiddling, though critics cite recent bugs, CPU spikes, clunky window management and UI regressions.1041recommend
- LinuxA free, open-source OS praised for total control, stability and wide hardware and software support, especially on servers; desktop use can still take extra effort and debugging.745recommend
- HaikuA free BeOS-inspired desktop OS praised for being extremely fast and responsive with a clean, consistent UI, though many say it's not yet practical as a daily driver.115recommend
- NetBSDRecommended for running on almost any hardware, including old machines, with a clean, well-documented design, though support for modern hardware and drivers is weak.100recommend
