It depends on what future are we talking about, imagine if Bitcoin reaches one million each (whatever if happens or not), it will be more convenient if we use Satoshi denomination, i'm really waiting eagerly for that moment
I was thinking along exactly the same lines. Altcoin traders think in terms of satoshis, so I'm surprised that option was not more popular. Right now 1/1000 of a bitcoin may be a convenient unit of measure for "normal" (common) transactions, but if BTC goes mainstream and the price shoots up in accordance with demand, sticking with satoshis for pricing most items will make a lot more sense.
