Microsoft ARM support CES presentation  (Source: DailyTech)
Windows support for ARM architecture will help Microsoft grab market in smartphones and tabelts

One of the big announcements from Steve Ballmer’s keynote was that Microsoft would be making a version of Windows that would run on ARM processors. This is a big deal for Microsoft, which has traditionally worked very closely with Intel/AMD with x86-based processors. 

The x86 architecture is seen as inferior to ARM in some markets like the important and quickly growing tablet and smartphone market where long battery life is an important requirement. With Microsoft stating Wednesday at CES that it would bring the Windows OS to market for ARM chips; it is an acknowledgement that Microsoft plans to grab for a bigger slice of the tablet and smartphone market with its software.

Today ARM's Tudor Brown told Reuters that support for ARM processors in Windows would help the software giant get a big foothold in smartphones and tablets.

Brown told Reuters, "With Microsoft, for some time it's been more a question of when, not whether, and finally it's now. We've been coaching and cajoling Microsoft for some time."

ARMs architecture is licensed to major players in the tablet and smartphone market like Marvell and Qualcomm, which are the companies behind some of the most popular processors in the smartphone market.

Brown added, "Microsoft needs ARM to have any chance of playing in that [tablet and smartphone] space."

I don't think that's the only reason. To date I haven't seen any supercomputers, high-end workstations, or even regular computers using ARM CPUs. Could it also be that ARM just has never been as powerful?

ARM is clearly sufficient for phones/tablets, but can it match Sandy Bridge in performance or even per watt? There's no doubt that we are entering a new era of ARM devices, devices which should be powerful enough to entertain the masses, but what about the high-end?

My last sentence was going to read:

"Will we see 100-core ARM laptops or 1,000-core workstations soon?"

That's because designs take 4 years from announcement to actual shipping products. Cortex A15 will start filling that gap in the future, but it was announced last year and won't be in products until 2013.

all the Blue Gene Super comps run RISC CPUs and ARM falls under that category.

http://en.wikipedia.org/wiki/Reduced_instruction_s...

and for super computers currently running RISC

currently there is still a RISC based system in the top ten http://www.top500.org/lists/2010/11
granted the other ones are usually x86 systems with GPUs but to date there is no shipping system that has ARM silicon specifically in any part of the system. On that part you are correct.

ARM is very efficient per watt and for die space. Currently ARM and x86 are made for totally different things. ARM is plenty powerful to power apps made for it, even modern desktops can struggle running complex webpages unless you have a fast system you you accelerate flash. my three year old desktop runs flash faster than my sisters September 17" MBP so she has to use my system for farm-ville. by the time we have shipping quadcore ARM CPUs im sure we will have better flash acceleration then perhaps you will be right in ARM and x*^ will be comparable or general desktop computing
