Use Satoshi's with the familiar "computer" prefixes Kilo (K), Mega (M), Giga (G) etc.
The point is not to appeal just to the techy mind - in which case you're absolutely right - but to take it out to the currency using masses. We should try to put ourselves in the shoes of our customers.
I agree. There is no easy solution. It is easier to use Kilo, Mega, Giga (and increasingly so as computer uptake increases) than milli, micro and nano though is my main point.
