Windows So, a rudimentary jailbreak for Windows RT made its way onto the web these past few days. Open source applications were ported right away, and it was confirmed that Windows RT is the full Windows - it's exactly the same as regular Windows, except that it runs on ARM. Microsoft responded to the jailbreak as well.

"Microsoft's somewhat official reason is that it can't create an emulation layer fast enough to run code compiled for x86, and they are probably right."

I wouldn't say they are probably right, ARM has done great job keep power usage down, but with that they sacrifice performance. You take even quad core ARM based cpu right now, it would be much slower then x86 based. A recent interview with rep from ARM maker, they he said "Intel can't match us in power consumption" but stopped short of fact they can't match Intel in performance. Although only thing that happened from that was 2 months later Intel put out an new Atom cpu that was in power range of most ARM parts, and has little better performance.

Anandtech has been really busy trying to messure and compare:

The latest ARM-chip beats the previous Intel Atom chip.

The latest Intel-chip beats the older NVIDIA Tegra 3.

It is starting to look like a proper race now.

There'are people who can create fast x86 emulator (and some are already doing that),
Microsoft just need to get out of their way.

Qemu is more-or-less the fastest one, but it still ain't fast. You possibly think of virtualization, which is not the same thing.
