^ this in fact I don't think they should add LEDS at all. Unnecessary lights everywhere at night drives me up the wall recently attacked every open light with electrical tape so it's not like Blackpool illuminations. If I want lights I will add them myself!
The only time I understand LEDs is white backlit keys when it just illuminates the characters for if you need to type in the dark and can't type without seeing the keys as I know a lot of people need to. They also need to be on a toggle though as I would never want it on all the time!
