Guys, this ARM thing isn't just about nVidias Denver project, not at all!
Did you even look at the Windows @ ARM video?
http://www.youtube.com/watch?v=xKc_XGuvNIkThat's on
*current* technology, not the ones 3 year away (but it's of course a good thing that a long term evolution plan exists, that's what I mean by ARM having a great support and momentum!
The current stuff is actually great!

And even on short term (within this year!) we will see new generations of ARM CPU's rolling out! This is the road map from Freescale:
Freescale i.MX Road MapOf course the other ARM CPU manufacturers have similar Road Maps (but maybe different philosophies on the included support controllers, etc)!
Genesi is
already working with a new, multi-purpose i.MX53 based motherboard (a single motherboard that can be used in various applications, like pads, laptops, desktops, etc). And while this still is based on Cortex-A8, it will probably be clocked faster than the current Genesi products (although that is a guess from my side), and have upgraded support controllers to do full HD (among other things)! It will also make things a lot cheaper than it already is! Even more power, for even less money!

Sure, nVidia has announced "that it plans to build high-performance ARM® based CPU cores, designed to support future products ranging from personal computers and servers to workstations and supercomputers". And that surely bodes well for the future, since others will follow as well! This promise real, heavy performance, never before seen in ARM territory!

However, ARM is *already* being used in low power servers in data centers, and while the market is young, the future is bright and big companies like Dell and IBM are very positive. And did you see Windows run, play media and run Office on the current ARM based machines in the MS demonstration above? Looks very good! Heck, current cheap, low power ARM CPU's could even be used to build super computers, like IBM did with their BlueGene by building a new system architecture around an array of simplified PowerPC 440 cores.
Add to that the future roadmaps of first the Cortex-A9 and then the Cortex-A15 that will over time bring:
• Speeds beyond 2.5GHz+, 14,000+ DMIPS
• 1-4X SMP within a single processor cluster
• Multiple coherent SMP processor clusters through AMBA® 4 technology
• ARM ISA
• Thumb-2
• TrustZone® security technology
• NEON™ Advanced SIMD
• DSP & SIMD extensions
• VFPv4 Floating point
• Jazelle® RCT
• Hardware virtualization support
• Large Physical Address Extensions (LPAE), meaning up to 1TB memory
Add to that all the various controllers that individual CPU manufacturers chooses to add. So I'd say that ARM is definitely breaking out of its old boundaries, with or without nVidia's Denver!
