Q:  Which of the following sounds better to the AVERAGE person:

Your meal comes to 2.5 ________.  

a)  bitmills
b)  millibitcoins
c)  millibits
d)  "m.b.t.c's"
e)  bits

Yes, a subjective question, but I think it's safe to assume a poll of the general population would show a preference for "bits" 9 out of 10 times - possibly more.
