I honestly think that Navi is still the more annoying "handiguide" of the Zelda games. I can see why Fi can be a nuisance, but I think she's still a little better than Navi. The only time Fi is ever really annoying is when she pops out to explain and give you a description of the new terrain you're on. You don't really hear her wanting to give you any info that often. Navi did it constantly and all she really did was give a bland and obvious explanation on where to go next. One thing I can't stand though about Fi is when your batteries are low and she keeps signaling you so she can tell you your batteries are low...because the red, almost empty battery bar that appears in the corner of the screen wasn't obvious enough.
