|Currently, Mac users who have need to run Windows software or want to run the latest PC games are often better suited to buying a PC for that purpose, rather using emulation software like Microsoft's Virtual PC or Lismore's Guest PC.
On Intel Macs, running Windows won't require hardware emulation, but rather just a simpler and much faster VM (virtual machine). Like Virtual PC, a VM runs a full copy of Windows, there's just no need for slow x86 to PowerPC emulation.
Some Windows software won't even require installing a copy of Windows; instead, Intel Macs will be able to run WINE, which maps a Windows program's Win-32 function calls to the native operations in Mac OS X. CodeWeavers' CrossOver, a commercial implementation of the open source WINE project, has already announced support for Intel Macs.
WINE is similar to the fictitious Red Box that was invented by speculative tech rumor mills during the early development of Mac OS X. WINE never made sense on PowerPC Macs because, well, "WINE Is Not an Emulator," and WINE would require a separate emulator in order to do anything on a PowerPC Mac.
On Intel Macs, WINE will be a functional alternative to a VM, except that it won't require a Windows license to operate. This is because WINE replaces, rather than runs a copy of, Windows. Certainly the availability of WINE will prompt Microsoft to optimize their development of Virtual PC on Intel Macs so that users will have a reason to buy a Windows license in order to run Windows software on the Mac.
