Non-mathematicians have difficulty picturing sums like 0.00014321 BTC, which would be 143.21 XBT if XBT=100 satoshi(s)
The transition would be even more seamless because people already started thinking in bits. If 1XBT=1bit=100 satoshi, it would all make sense.
I like this too, and think it is the best option.
Me too. I started supporting this proposal sometime earlier this year. It still feels right.
It also seems opposition is much less fierce than last time the topic bubbled to attention.
However, an alternative is to try and get two ISO codes, with XBT for 1 bitcoin and XBU for millionths (which would be used in existing financial systems).
I can't quite get myself to like that.
btw, the "bit proposal" is supported by Gavin now (for whatever that's worth):
