Who would want to say "this item costs 0.0000000001 bitcoin" compared to "this costs a dollar"? No one.
So no, people do not want to deal with decimal points. They like dealing with whole numbers. I'd like to see someone go to a bank and request $0.00023 dollars. lol
Call them Satoshis or mBits. Go to the bank, transfer 100mBits, go to the store, buy groceries. "That'll be 72 mBits, sir/ma'am"
