mobile platformThe hardware/software environment for laptops, tablets, smartphones and other portable devices. Windows and Mac dominate the laptop world, while Apple and Android rule the smartphone/tablet universe. Windows Phone is slowly gaining market share, and BlackBerry 10 is expected to make its mark. Symbian used to be the predominant smartphone OS worldwide.
Laptop computers use x86-based CPUs; however, the overwhelming majority of smartphones and tablets employ ARM processors. For example, Apple's systems-on-chip (SoCs) include ARM processing cores. NVIDIA's Tegra, Qualcomm's Snapdragon, Texas Instrument's OMAP and Samsung's Exynos chips are all based on ARM chips.
Initially used for netbooks, Intel's x86-based Atom CPU migrated to the tablet arena. See Intel Atom, ARM chips, mobile compatibility, mobile device vendor control and platform.
