Windows The rumours about Windows possibly being ported to ARM has left a lot of people bewildered; why would you port Windows NT when Windows CE 6.0 is a perfectly capable operating system? Putting all the pieces together, it's actually quite clear why you would want Windows NT on ARM: servers.

I just don't see it

Windows on ARM? How should that bring an significant advantage to Microsoft? I don't see a big issue porting the OS to another platform but all the applications? No way. It will take ages. The business world that is closely with Windows is not likely going to change quickly. Huge applications on Windows are mostly not written to be that portable. And even if they get ported to ARM, it will take a significant amount of time till they run as smooth as they run in x86. And on top of that keeping an x86 and an ARM version of an application takes time and resources. Look at the big players and how the struggle in getting applications to run on multiple architectures. IBM is such a good example. They offer for example their Lotus software line on many platforms and still they have not the same level of support for every platform. You can get Lotus Notes client for Windows, Linux and for Mac OS X. But some things are only offered on Windows (for example the Lotus Domino Administrator or Lotus Domino Designer). If it would be so easy as 1-2.3 to port an application to another platform (as many of you state here), then explain to me why IBM (without doubt one of the big players) does not port all their applications to every platform to the same extend as they do with Windows applications?

I personally just don't see that huge advantage of having Windows on ARM? Probably the power savings are (for now) huger on ARM but most business dependent on Windows will not that easy change to something new. And those one that need to squeeze the last money out of hardware and software are anyway not the one running Windows. They mostly run either Linux or a BSD variant. Or is any one here thinking that Windows on ARM is going to push Google to switch to Windows servers? Probably not. Big data centers try anyway to decouple from Windows (if they can). Windows might have advantages (depending on what you need) but it is a OS with a not so low price tag. How could/should Windows on ARM change that picture?
