Its not about looking cool its about its usefulness. There is a 100 examples like that. I have a home office and are in and out all day, if i go to the toilet or letterbox or whatever when i come back i can see if missed something without having to pickup pushy pushy slide. Also being a business phone after hours/weekends it goes on block mode except for family.
I had a M8 for a few weeks but the light on HTC phones only blinks for 5 mins and is harder to see, sold it for a S5.
That's how much i need the notification light.

you should of put it in the iPhone forum with all the iPhone fans, what did you expect they only come in here to stir the pot. It was bound to hit the wall
My wife and son have iPhones so know the drill.
