It is way too early to be denominating paymetns in satoshi units. Wait until bitcoin is worth $1million or so so it makes more sense. Right now the best thing to use is mBTC for the sake of simplicity.
Disagree. mBTC, bits or whatever is just asking for people to be placing the wrong decimal somewhere and ruining themselves. I still get stumped by stuff priced in mBTC
There's BTC. There's Satoshis. Anything in the middle adds confusion and will eventually be abandoned in favour of Satoshis anyway. Much better to go straight from one to the other.
