Windows RT is developed specifically for ARM-based devices, whereas Windows 8 is for Intel X86-based PCs. The ARM processor allows hardware manufacturers to build Windows RT tablets and laptops that use less power--and cost less--than their X86 counterparts. According to Lenovo, which plans to sell both Windows RT and Windows 8 machines, RT-based devices will cost $200 to $300 less than those running Windows 8, Bloomberg reports. And while it's too early to say how well Windows RT devices will outperform their Windows 8 counterparts, battery-wise, both will reportedly stay on for more than 320 hours in a network-connected standby mode, Microsoft says.
