I need to talk about #Linux.
There's things being different, like how the file systems are structured, or how GIMP works different than Photoshop, or how different the UX is for Gnome and KDE compared to Windows. I find ALL of those aspects valid, and worth investing your time into.
But there's that, and there's having to grind your way through the command line and editing system files for hours because it's your only choice and there's little documentation around the software you use.
