I guess you're right, it does put them on an even footing. Actually the scene in the TARDIS this week, after she landed it, showed him getting one back on her by going outside and telling them exactly where they landed without benefit of a computer or an environment scanner.

I do love their banter, though. And I think she's good to have around, especially with Amy as the Companion - since she's new to the Doctor and can ask all the questions that are on our mind.
