I tend to use them as audio-only devices, as the way they're presented in the story suggests that's all they're capable of. Various NPCs throughout the storyline contact you via Linkpearl, and despite a visual being advantageous in various situations (particularly in the final dungeon...) we never see it happen. What we do see as an example of Linkshell use is Raubahn appearing to touch his ear and speak to a soldier remotely. There are likely other instances in various cutscenes, but I just woke up and my brain may still be slightly sleep-addled.
