So the underlying question is "what unit should we switch to now", correct?  
I'm a Bit hater for a few reasons...

1 - "Bits" would almost certainly be confused with "Bitcoins", because, why wouldn't they be?

2 - The name "Bit" + "Coin" was not chosen arbitrarily. Removing the "Coin" and terming them "Bits" seems to refer only to Binary Digits (and adds another layer of confusion... we should say 1 Bytecoin = .125 Bitcoins and really mess with 'em, huh?)

3 - At the current exchange rate, it seems an unnecessary leap to begin using the micro- metric (~ a fraction of a penny).

If we drop "Coin" for less syllables, "centibit" or "millibit" are much better candidates.
"I just bought 100 millibits for 40 bucks!" ... "I just bought 100,000 bits for 40 bucks!" is a little excessive.

Just my 2 centibits
