Well I tried to be neutral about that, for just the reason you mention. 
(I don't actually call it a disadvantage, I just point out the 
behavior.) To be fair, I think it actually *is* a disadvantage, so 
perhaps my thoughts on that are clouding my ability to be objective.

How about adding the following to the second-to last sentence, "... 
looks up, as it would using the traditional root hints method."

Does that sound more balanced?
