Mobile is dominated by cost. Qualcomm, Samsung, AMD have all tried their hand at good ARM processors but the perf gains and costs have never been good enough to sell mass market devices. Apple is the only one remaining, and they spend a lot per chip... it would be about as expensive as an Intel chip, if not more expensive, if sold separately. ARM is not a panacea.
