Sailfish on the N9 is pretty much useless. As aspergerguy says, forget it. The N9 is a beautiful device but not as an entry to the Sailfish world.

I find it curious that you consider the N9 and Jolla C. The two are on the opposite sides of the size scale.

Would you consider Jolla 1? That would be the genuine experience and they can be obtained quite cheap these days. If you could wait until after Christmas, I could sell you my wife's. She has never grown into it and I may get an Android phone for her for Christmas, making the Jolla available.

(BTW, "I am alive in Spain" sounds strange in English. You normally say, "I live in Spain.")
