Why blinkenlights ?

I am currenly contemplating what kind of IO to put on my coming i8008 
system : what is it that makes blinkenlights (i.e. leds and switches ) 
seem so attractive ?

It must be about the worst possible way to interact with a computer...


So why is it then  that almost all early micros had them ?

a 7segment display with keyboard ( as in a H8) is clearly more usable, 
and would have cost nothing more. Or were early eproms (for the monitor 
program) that expensive ?
