It's useless and unused because it contributed NOTHING to the plot/script. What was the point? We didn't even see it used. It was just a belt buckle as far as the audience was concerned.
And I thought the belt monitors looked cool. They didn't "take away" from the uniforms.
Well, to me they did. And you can't compare those to a bridge monitor. Bridge monitors weren't in your face all the time like the characters are.
Oh well...let's agree to disagree. I just think if it's on the screen...or rather an actor...it should have a purpose that serves the script.
But, I'm crazy that way. I'm crazy in a lot of other ways too...but I am crazy like that about pointless and unused technology attached to characters.
Just looking "kewl" isn't enough for me.
