From recent news, it seems that Microsoft banned booting of Linux or any other operating system on ARM based Windows 8 devices. From this decision of Microsoft, it seems that they are ready to war with GNU/Linux operating system. Due to the UEFI secure boot protocol, any other OS rather than Windows 8 can not run on ARM based devices.
If you buy any hardware, it will be yours and you can run any operating system of your choice. Now a days ARM is used not only in mobile device but also in tablets and notebooks. Microsoft attempting to kill GNU/Linux from ARM based devices. It sounds very pathetic and insane. So they should back off their decision otherwise it seems that there are starting of war between Windows and GNU/Linux.
