True. I have a dedicated machine (33mhz or 133mhz with the magical turbo button) for DOS gaming. 5.25" floppy drive, CD-ROM drive, and everything that covers most of your older games.
For a DOS laptop, an old Toshiba Satellite Pro works well. Many (if not all) have a Yamaha chipset for the sound which won't let you down. I used one for a while as my car MP3 player.
