After years of insignificant adoption among manufacturers, Intel is apparently throwing in the towel on smartphone chips. The company's ultra-low-power Atom line of processors has had a tough time competing with low-cost players like MediaTek and, obviously, the incumbent mobile SoC juggernaut, Qualcomm.
