"As pointed out in this EE Times report, entitled "Dell has
dragged the Linux-ARM Trojan horse inside the Wintel PC," Dell is
offering a processor-plus-OS subsystem separate from the main
Windows-Intel system.
"The goal is to give users instant access to e-mail without
booting up the operating system and extend battery life by running
Linux on a very low-power ARM processor. Basic ARM processor
designs are licensed by U.K.-based ARM Holdings to companies like
Samsung and Texas Instruments, which then manufacture the
chip."
