The 1 minute confirmation time makes it a winner(I prefer to use XPM than those "cheap" scrypt cloneCoins) for those who do lots of arbitrage, it's currently in 3 or 4 exchanges, so moving funds between them with primeCoin is the best option so far. Wait until it hits BTC-e, it's price is gonna explode! 
didn't BTC-e say no for now?I don't know. Maybe after a test-period they will reconsider it. XPM looks better than all the scrypt altCoin so far.
