Apparently Apple and RIM are doing something right:

The two accounted for only 3% of all cellphones sold in the world last year but 35% of operating profits, according to Deutsche Bank analyst Brian Modoff. The disparity will become even starker this year when, he estimates, the two will take 5% of the market in unit terms but 58% of total operating profits.

You don’t always need enormous market share to have a very healthy business.
