ARM-Based Servers Coming In 2011
markass530 writes with this from the EE Times: "Arm Holdings chief executive officer Warren East told EE Times Wednesday that servers based on ARM multicore processors should arrive within the next twelve months. The news confirms previous speculation stemming from Google's acquisition of Agnilux and a recent job advertisement posted by Microsoft. East said that the current architecture, designed for client-side computing, can also be used in server applications."
I favour anyone who can build and deliver a laptop with 12 hours battery live. In addition, a low power ARM server for office work (small and middle enterprise) is a nice to have, too. I think most users don't give a piece if it's x86 or ARM, as long as their applications are running and it's a good deal. I, for myself, am really glad finally see any innovation in desktop CPUs. I thought in 20 years we will still be using x86 compatible CPUs.

The problem is more the apps, windows itself could probably be ported without too much trouble but most windows apps are likely to have code that makes x86 specific assumptions and are closed source so only the vendors can fix them.
Emulation is an option but unless arm cores start performing a LOT better than intel cores of a similar power envelope that won't help much.
note: i'm known as plugwash most places but i screwd up registering that here somehow in the past and now can't register
ARM currently supports 4 GB of memory since the ISA is 32-bits. Full 64-bit addessing support is years away. Interim "PAE" extensions will be just as ugly and unused as the x86 PAE.
The MIPS/Alpha/PowerPC failure of Windows was caused by 1 thing only:
The disgustingly cheap price of the Pentium Pro.
For $10,000 dollars you could have the same (two socket) performance as a $40,000 Netpower, or a $30,000 DEC Alpha.
Intel's volume and engineering skill is what made porting to anything except Intel a waste of time, except on some very special applications.
The fact that MIPS/Alpha/PowerPC where all 64bit CPU platforms back in 1996 should incense anyone who bought into the Itanium myth. Thank GOD we had AMD around to force Intel to move to x64.
