Cost. The wikipedia article says that the cost is similar to the cost of synthetic sapphire. For a cell-phone sized sheet of sapphire, the cost is apparently 10x as much as the cost of a similarly sized piece of chemically hardened Gorilla Glass (source). Most customers would rather save 90% of the cost and get a slightly inferior product that they have to replace sooner.
