One of the things that will help end-users get ARM going on their ordinary personal computers is the love of GNU/Linux or Android/Linux. There are moves to port Android to x86 but now there is IcedRobot which seeks to create a Davik virtual machine on a normal GNU/Linux system. This is all good.
One big advantage of IcedRobot is that it will use OpenJDK on the desktop so Oracle will be toothless. Chuckle…
Either way you slice it, all kinds of Linux-based systems will be running on PCs of all kinds. The lowest cost will be ARM in your PC. The highest performance may still be AMD64 and in the middle x86, none of which require that other OS to slow us down, force reboots or gather malware from the universe. The ability to run all the cool Android apps on desktops will be very attractive for those already in love with their smartphones.
