Sorry to be a stick in the mud (again), but when I saw the scale line width options, I thought we finally was going to see:

* Ability to scale objects but retain line width

And with that, perhaps:

* Ability to scale rectangles, but retain the corner radius
* Ability to rotate objects, and retain the angle value

The new guy at the company I work at uses InkScape as his main app. He'll have to try Xara to update the stuff I produced, so it will be interesting to hear his feedback.

I wonder which package will manage a mature native OS X port first... InkScape or Xara X?
