They're generally not powerful enough to run CAD software/Video editors/Photo editors/DAW software, and most games that bitch about anticheat will run poorly even on a gaming laptop.
If you really do need portable CAD, photo editing or video/music production, you're generally gonna have a better experience on a Macbook, and for day to day usage, light gaming or light productivity, there's really no downside to using Linux (A Macbook works for this too, but is a bit overkill).
