The numpad location just seems too bizarre. For me, I'd have to twist my head around all the time or risk lifting the mouse up to see what I was pushing. Maybe for those who read braille? But then you wouldn't be gaming, or do the blind play video games?

trust me, it will take you less than 2 minutes to get used to it. The profile of the buttons makes it pretty clear which one you are touching!

but i don't know why it must have a led...

See (or feel in this case), Braille!!! https://en.wikipedia.org/wiki/Braille

For the same reason that cooling fans have LEDs I suppose.
