Inkscape is actually one of the few FOSS apps that is actually pretty intuitive to use. In fact, way back when I first started using vector design tools, I found it more intuitive/had better feedback than Illustrator (same thing can't be said about GIMP vs Photoshop). Inkscape really is great, but I have one huge gripe: I'm sure there's a system to it, but the file export name never stays what I want it to be...

People are confusing UX with UI. Inkscape UX might be better for many people but it would be hard to argue that Inkscape UI is better - it got better recently but it's still far from blender polish.

With a much simpler set of tasks to accomplish.
