The silly thing about all these dozens and dozens of threads about this
very same subject is that
nothing is stopping you from doing exactly what you want to do!
If you feel that your needs are met by always talking in terms of mBTC then just do it. You do not need my approval, you don't need anyone's approval. If it catches on it catches on.
If you like satoshis better then use them.
If you like nBTC - my suggestion - they use them.
Why all the threads? There is no need. Plus, they do not accomplish anything. The market will eventually decide this.
Another bunch of theads that are pointless are the "what should we call them?" threads. "Mics", "Micros", "Millis", "Bits", "Unis" (I know, WTF?), etc. These threads always come across as someone trying to think of a cool nickname
for themselves. Nicknames are not forced on the public. The public comes up with them and/or accepts them like "bucks", "greenbacks" etc.
The point is: just start using the units and nicknames that you like best and see what happens. If people like the idea they will follow suit.
BTW check this out:
http://bitcoinity.org/marketsmBTC. They just
did it. No hand wringing thread. I kind of like it. There.
