I use it mainly in AI stuff where I need to work on binary strings in an 
explicit manner.

I also use it a lot for stuff like this:

x = {10,20,30,40,50,60}
y = {30,10,25,40,60,65}

z = (x < y)*x + (y <= x)*y

z is now: {10,10,25,40,50,60}
(taking the smaller element from each sequence -- the "=" is in the 
second half but not the first so equal elements will only be taken once)

Yep, it's useful.
