I once had a pocket calulator with all the keys black except the [-] key which
was bright orange. Thus illuminated the [-] key was hard to find for those
unfamiliar with that device.

a for loop promotes the code for finding the next value of the counter to
the header of the loop (where it should be easy to find - like the orange
key)

a while loop only makes obvious the exit condition of the loop.

with a for loop you can see on the for line whaere it starts,  how it
proceeds from one counter value to the next, and where it ends.

of cource if you're writing obfuscated code the for loop also gives more
options :o)
