>I'm about to use the currency type in an important app. I seem to remember when this field type first came out that I had some problems with some commands like round(), or transform() or reporting layouts - I can't remember exactly. So....
I can give you a specific example - I got something similar.
round($1 * 5.12345, 3)
You expect: 5.123
You get: 5.124
Reason: First, the number is converted to currency, which is limited to 4 decimal places, that is, 5.1235. This is then rounded up to 5.124.

Mainly, if a calculations involves a currency value, ALMOST ANYWHERE, the entire result will be currency. If you need more decimals in some calculations, use mton() to convert to numeric.
If you know what you are doing, I don't really see any reason NOT to use Currency, when it makes sense. I have been using it for quite a while. Some workarounds, especially the use of mton(), are required here and there.
