Price it in sats, force plebs to do their own conversions if they so desire. Adding dollars-and-cents in parentheses is unbecoming in my opinion...and I have very strong opinions!

It's useful for quick understanding of value. I guess Monero needs the equivalent in sats to avoid using the 0.001 type of values that are difficult to convert. I guess most people use monero alongside with dollars and euros in either case, it is mostly because of having it private digital form.
