Hardware, Embedded Systems So, we have Intel and AMD. These guys are doing pretty well in laptops, servers, and of course desktops, but when it comes to mobile devices, they've so far been unable to adapt the x86 architecture to the stricter requirements that come with those devices. ARM, on the other hand, pretty much owns this market at this point. And you know what? It's time for Intel and AMD to get worried - really worried. ARM has just announced its Cortex-A15 MPCore chips - which will reach 2.5Ghz in quad-core configurations.

afaik the windows nt kernel is very portable and they probably already ported it to arm, the real problem is not the os itself, but all applications would need to be ported too

Virtualisation. If ARM really takes off that way, MS will not face too many problems. They've prepared for this, trust me.

I don't think that's really a solution, Thom. Running an x86 application in a virtualized environment already takes a performance hit even running on an x86 architecture. Emulating an x86 environment on a non x86 architecture involves vastly more overhead due to the amount of instruction translation that goes on. The performance hit would be huge, something we already see while using QEmu.

If MS want to compete with Linux and the BSDs on ARM, they would need all of their server software partners to port their apps to ARM, no doubt about it.

This is an area where FLOSS will really shine.

AFAIK that's exactly what the Alpha version of NT used to do, emulate x86 for all those non native apps. In fact they have something similar for old 16bits apps and for 32bit apps on 64bit systems (the WOW stuff).

That's also what Apple did when they transitioned from PPC to x86.

For MS it would be a way to wait while they push developers to use .Net to write portable apps.

They definitely have the expertise in house so it's just a matter of whether they're interested in helping ARM succeed.

Or the rumoured Windows successor which is built with a managed code userland.
