The whole unit change seems so disruptive and difficult to coordinate now -- do we really want to have to deal with another one later when there are way more people to try to coordinate? I really think we should look to the endgame and figure out where we want to be.

I'd propose moving to uB (micro-bitcoin = 1e-6) as the standard unit now and forever. For now, it can be referred to as uB or uBTC, but over time, once it's ubiquitous, it should just be called a bitcoin. Because the smallest unit is the satoshi (1e-8), this means uB-denominated prices would get 2 decimal places maximum, which is the most that any consumer wants to deal with anyway.

At the same time, I'd propose inverting the exchange rate, so instead of quoting uB/USD = .00013, it would be quoted as USD/uB = 7692. This is exactly the same way Yen are quoted relative to USD (USDJPY = 100.66), and is also the same way other private virtual currencies such as WoW gold are quoted.
