will you be able to run Mac osX and Windows XP simultaneously??????avoiding having to emulate a la Virtual pc
With the protected memory areas, there is no reason Windows could not be run as an application under OSX, methinks.
On the same machine? Yup. At the same time .... well, with caveats ... performance being foremost.
You can make a dual-boot disk, and have your machine boot windows, or have it boot Mac. There are companies working that will allow the Mac (spelled 'Linux') OS to run Windows software programs, so your OS will be Mac, but your programs you have purchased will run on the new Apple OS.
There is only 1 catch that I'm aware of. Apple has enjoyed a non-competitive stance against pirates because you just can't find PowerPC motherboards and PowerPC chips out in the wild. However, you can find BILLIONS of x86 motherboards and processors. A forsee a plethora of Mac 'clones' running the MacOS on non-Apple motherboard designs. The hackers are at work already on defeating the security measures Apple is building into their x86 OS X release.
Yes, but it will still require a virtualization layer to simulate the Windows boot process before the capability becomes active, along with a Windows license and media. Rumors exist that Apple is secretly working on a seamless virtualization layer so the Windows applications could run right within OSX, providing the Windows compatibility as OSX boots but still requiring the Windows license. Most optimistic guesses of that being available are about 2 years away, if at all.
