I'm not particularly enthusiastic for the mBTC proposal but on the other hand I don't see it doing any harm.
Talking about buying a few mBTC for ~$1 each sounds way more attractive than buying 0.001 BTC, which feels like buying something worthless.
So I think it's a good thing for BTC to continue to become more mainstream!
Probably means: "The market price is above what I believe it should be."
Not: "$1000 is too much money for me to spend."
