Drats. I give it a go every handful of years because I want it to be great, but that's my experience every time, too.

I still hold out hopes, since Blender used to be the same way. When I last tried Blender, their keyboard shortcuts and scene navigation were clearly developed by someone who thinks that using emacs is a good idea, and that vi never should have been improved.

But they're a serious pro tool now that has a foothold in the 3D industry which I would not have predicted back then.
