I think the whole point of NOT running Windows on a VMWare type of setup is that it is slow, because you don't have direct hardware access. It doesn't matter if it's the same architecture, virtual machines suck. The benefits of dual booting are obvious for corporate environments using their Windows only software, as well as gaming in Windows. I would rather dual boot up any day then then have a virtual machine going. Think of Wine for Linux. It sucks, because it's trying to emulate Windows, and it's running on x86 hardware but that doesn't matter because it's
still emulated and therfore
still slow. The advantages for dual booting should be obvious to everyone. The only thing missing is Windows XP support for booting with EFI. I think it's just a matter of time before we see a hack for this. Somebody somewhere will make it their mission to be the first to dual boot Windows XP and Mac OS X on a new intel Mac.
