sPhotoshop, Illustrator, Indesign (Scribus is not a replacement for people doing it on a daily basis) Acrobat Distiller, Premiere, and AfterEffects. Also, Photoshop Lisghtroom and DxO. There are also a myriad of smaller apps like image resizers. Also, I'm at uni, so Endnote would be nice. Having a look at my startmenu more than 50% of the apps are not supported on linux. My whole ecosystem would need to move over to allow me to change. Note: I have been running linux on one laptop or another since the 90s.
