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


In the case of Windows, not only the applications, but also the drivers. That is the ultra-critical bit.

Linux has source code for its drivers, as does Mac OSX et al.

Windows doesn't. Microsoft leaves it up to the equipment OEMs to write the drivers for Windows, an as a consequence, Microsoft doesn't own the source code.

Not only is there a problem in getting a whole raft of other companies to port applications to Windows on ARM, it is further compounded by having to get a whole raft of equipment makers to port drivers to Windows on ARM.

In addition consider that printer, scanner, your phone and your camera ... all of which you now use with Windows ... they all came with drivers on disks (probably CDs) ... x86 drivers, x86 binary-only drivers. They won't work with any new Windows on ARM computer that you buy.

In addition, all of the Windows applications that you have already bought (some of them very expensive) ... they too have been bought as x86 binaries. You won't be able to mover them to your new Windows on ARM machine, you will have to buy them over again.

Oh oh.
