So you want bitcoins for mathematicians only? Change the format when we are allegedly at the tipping point of mass adoption?
Gold costs $1400 an ounce. People live with that. Nobody changed the default way gold is represented.
Its a problem that doesn't need solving.
Gold was not used as currency at $1400 per ounce.
What happens when you want to price something that costs 0.000739 bitcoins? Writing 739 uB is a lot easier for the non-mathematician.
Many average users do not like the idea of spending $610 on one bitcoin, so this is a barrier to entry for the average joe.
A price of $0.61 for 1000 microbitcoins seems much more reasonable.
Also note that this thread is in response to this other thread that suggests satoshis as a base unit instead of microbitcoins:
