Curious if that wouldn't be a cheaper way to get Vista than waiting to buy Vista when it ships? What does everyone think? Is Business Vista the top version like XP Pro? Can I get an opinion from the Windows folks please? Won't the top Vista sell for more than $199? Is Business Vista the 64-bit version? Or is all of Vista 64-bit anyway?
The top of the line Vista is Ultimate which has the media features of Home and the enterprise features of Business. All versions of Vista come with both 32 and 64 bit versions. But, unlike OS/X you need to choose to install one or the other, and in the x64 version you need all new drivers that are 64 bit and apps that do not break under 64 bit (which is a real issue). Under OS/X the kernel and all drivers are 32 bit and the same as before so all the existing devices work. Applications can be either 32 or 64 and both run under the same OS with no emulation. So under OS/X there should be no more breakage in going to Leopard than any other release, while Vista is going to have serious issues in migrating to 64 bit.
