Tesla can't make money just on luxury cars (the stock is pricing in expected discounted future profits, not current losses). The "X" is really a make it or break it for the automotive segment of the company, and most analysts believe it will be a big winner.
Is the "X" a model that is good for skiers? Probably not, due to ski rack/roof rack issues (unless someone goes with a rack that attaches to a trailer hitch). Still, it is an electric model for the masses and if it like the "S" it will be well made.
It is very possible the majority of "X" owners will be women: http://www.bloomberg.com/news/articles/2015-09-18/tesla-asked-women-what-they-wanted-and-came-up-with-model-x-suv
