I vote for Satoshi
Me too. I've been talking about satoshis for much of the last year.
By the time bitcoins are worth $100,000 each, milliBTC will be as large and cumbersome as whole bitcoins are now.
We already have have satoshis which are small enough for the foreseeable future.
In the early days people had no problem referring to prices in thousands or tens of thousands of bitcoins (e.g. pizza) so it shouldn't be all that hard to say a pizza is worth around a million satoshis at today's prices.
