The only thing I don't like about NEO is you can't send fractional coins.
If each NEO is worth $1 million USD, then no one can send $100,000 worth of NEO. That's the bad thing about NEO.
But you can already trade fractions of NEO on exchanges (like Bittrex). Just won't be able to send them to NEO wallet, so as long as exchanges will also distribute gas to NEO holders, it is not such a big issue. That is if you trust them enough to hold your coins there.
