Also, did you expect Obi-wan at the end of ROTS to look at the screen and say something like "See, I didn't technically own any droids"![]()

No, but I would have liked to see Obi-Wan's house just once in the PT... and we could have gotten the sense that he lived simply with very little ownership, especially droids.
It's a small thing. They are all small nits. But they add up.
