Intel Virtualization Technology in Yonah
One reader points out that one significant new feature in Intel's upcoming Yonah Processor is "Virtualization Technology". Intel describes it as "allowing a platform to run multiple operating systems and applications in independent partitions."
The examples of use Intel provides include uses for administrators performing background system upgrades as well as separating business and personal use environments. The most interesting potential use is described here:
Potential uses under Apple's implementation of the Intel processors, of course, include the possibility of launching multiple operating systems, such as Windows and Linux, alongside Mac OS X. Alternatively, Tiger's Fast User Switching could be expanded to provide completely independent environments.
This Intel presentation slide posted on Anandtech's article from Intel Developer Forum 2005 confirms that Yonah is expected to include Virtualization Technology.
This technology brings back up a tamper-resistant code patent which Apple was recently granted. The patent description curiously also had a description of the use of multiple operating systems:

Home users could create virtual partitions isolating multiple user environments such as dedicating resources to a PC game, productivity, and personal video recorder-type environments

Apple also talks about securing the code while interchanging information among multiple operating systems. Linux, Mac OS X and Windows are called out specifically in the filing.

Everyone keeps talking about the dual core aspect of Yonah, but perhaps the best feature is VT, Intel's Virtualization Technology. According to this article, VThttp://www.nordichardware.com/news,2670.html is basically VMWare on a chip -- meaning that the new Intel Mac's will be fully capable of running OS X, Windows, Linux, OS/2, whatever, simultaneously in a system much like fast user switching, all with hyperthreading and dual core capability.
So everyone who keeps asking "can I dual boot?" ... "will there be a Virtual PC" ... you have no idea. This is going to be so much better. And as for the naysayers who cry "how do we know Apple will allow this?" remember Brian Croll's comment that Apple will not create any hardware to block users from installing Windows.
Finally, as for the persistent, annoying “why would you need to run both” comments, please just shut up. I have a PowerBook for 99 percent of what I do on a computer, but I also like to play Full Tilt poker, I run an Action PC Football league and play in a Diamond Mind Baseball league. These three pieces of software have required me to keep a 1998 IBM Aptiva connected (along with my PowerBook) via a KVM switch (and yes, a 7 year old computer IS better than Virtual PC) and I’m so, so sick of that ugly black box. When Mac on Intel and parallel OS’s come out, I’m going to sledge hammer the IBM.

Dual Core iBooks (please) i don't care about running Windows(i know some do) and that it will be cool as an extra but in the logn end it does little for me

They'll never be dual core ibooks :D Dual core Powerbooks, ibooks will probably be out in june or something with single core yonah....
Anyway, what this VT technology does is enable x86 to function better with a VM. There are certain things about x86 that make it very different to run 2 OS's at the same time on.... x86 will only allow the primary OS to run anything in kernel mode, when the secondary OS runs code in kernel mode it has to emulated by the VM program. So a program like vmware actuallly has to emulate some x86 instructions even when running on an x86 CPU.

That sounds pretty sweet and increases the idea of a dual (or trual (triple)) OS's booting on MacTels.

Of course this one gets on the front page and my post about the same topic over a month ago only got a few replies... :rolleyes:

Why would you need to run both? :rolleyes:
;)
Millions and millions of switchers will have a no-brainer,
painless way to switch over to Mac! This shall complete
the pieces to the winning combination!

A possible solution we are looking at is running OS X as our main OS and Windows for a proprietary program. This way the Windows OS could be configured not to use the internet and thus isolate it, while OS X, could be used for all other business applications (email, word, excel, ect.). Security is a huge concern where I work and my company would switch to OS X if it could run our proprietary applications. This would allow us to work around that.
