One problem with the mining (or "airdrop") with a phone is about the minimum coin for trading on exchanges. You may not be able to trade ETN with less then $5-$6 (there is transaction fees to send the coins). So people may have to mine it maybe for 6 months before they can sell it. Also they need an enough powerful smartphone, else they are going to wait a lot more.
But if one ETN gets more valuable, it can be good to mine some in case of a price increase.

I wrote the same thing a couple of pages ago
For the masses selling the coins on the exchange will never be the best option. We need the partnerships with mobile carriers and other merchants and app developers so the coins are directly spendable, then average users wouldn't have to deal with the stupid exchanges.
