It would especially be useful for creating models to make normal maps and texture bakes from. I think Blender has that, too.
But the interface steepens the learning curve for me...

I'll get it sometime

....um it's not that simple,be sure to unwrap it in LithUnwrap or some other UV editor. That way the baked texture and normals will fit the low-poly model...
