Text from @mikehearn really makes sense only with pennies. So I modified his text to at least make it clear that this scale isn't garanteed to work in the future. (Will change "penny" to "pennies" though).

With journalists starting to focus on "non Silk-Road" use of Bitcoin, I think we shouldn't delay the publication of the page. Mike said he wanted to rewrite the page soon anyway and I pinged him about this.

If current text isn't good enough, perhaps the next revision could be similar to:

    Bitcoin can process payments to the scale of a dollar and potentially much lower amounts.
