I couldn't disagree more about the "bits" thing. How does introducing another named unit at an arbitrary decimal point make things simpler or easier? Especially with a name like "bits" which can refer to a bunch of confusingly related topics: data storage, information, cryptography.
If you are confused by the simple idea of using "bits" as a shorthand for microBitcoins then you must be totally confounded by all the following terms (in order so as not to confuse you too much): penny, cents, nickel, dime, bit, quarter, buck, a nickel bag, a dime bag, a Jackson and a Benjamin.
I am sorry if the previous sentence left you drooling on the floor in total mind numbing confusion.
I honestly have no idea what a nickel bag , a dime bag , a Jackson or a Benjamin is...
I find it easier to use mBTC or uBTC than Bits, as those are SI units. (easier for everyone not using the Imperial system)
When discussing Bitcoin, I usually refer to amounts 0.01 BTC or more in BTC itself, everything between 0.01 mBTC (0.00001 BTC) to 10 mBTC in mBTC and anything lower in Satoshis.
This is really not an up and coming problem. For the time being, 0.01 mBTC is easy enough to say and is half a cent, so Bitcoins and milli Bitcoins are enough.
Talking in uBTC and Satoshis don't really make sense at the present time to me. I can understand how much they are, but 1 uBTC is lesser than a thousandth of cent, too less to need to use currently.
