So what are you using on the desktop and how long have you been using it? I’ve switched to Linux / open source software a year ago and especially learning programs (design / media tools in my case) was super painful for some time. But I had the motivation of not wanting to use an OS that tries to spy on me and getting away from a super shady monopolist (Adobe) as a motivator that kept me going. Sure there are still some things that get on my nerves but those exist in Microsoft’s (and Apple’s) and Adobe’s products as well.
I know you’re trolling but I had to look it up:
