Norwegian - future standard for airlines in Europe?

My first time being online from European air space. It is the truth I am the most  happy now - it is great weather, I am spending more than a week in Stockholm, clouds offers me wonderful show outside of the window. But my first flight with Norwegian is stunning surprise. After experiencing all the European lowcost and few ordinary ones, this is a great change!  Nice uniforms for stewards :) (believe me, nothing to compare with Ryanair's boiler suit), onboard wifi! , comfort of B737-800(plenty space for legs). And great value for money (40 Euros for 1 way flight, no extra charge..).
