franky1 just beat me to it. For nearly forty years I've somehow managed to function in a dollar economy despite the fact I'm handling pennies, nickels, dimes, and quarters every single day. This satoshi naming issue is overblown. If people want to use it, they'll make an effort to figure it out. Of all the things in the Bitcoin universe, the decimal notation and naming is the least difficult to explain to a n00b.
If my wife can figure out the g/s/c conversion rate in World of Warcraft, she can figure out BTC when the time comes.
explaining it is one thing, remembering it, and using every day is another. its not practical
Imagine if bitcoin was dollars for a second.
1 DTC = 100.000.000 Dollars
This is fine untill the Dollars get enough value, then you need new denominations that have less Dollars in them. But instead of basing the new denominations on the previous one, base it on what it actually represents, which is an amount of dollars. I guess its harder to explain than i thought. But basically there are about 2.1 quadriallion atomic units of bitcoin, in which about half have been found. Bitcoins denominations should represent the amount of atomic units of bitcoin they repsresent, not which fraction of BTC they are because then we end up with a confusing chart.
