Windows VISTA basically got 2 major platform:
1. 32 bits Windows VISTA (x86)
2. 64 bits Windows VISTA (x64)
As the 64bits software under Windows VISTA environment is not yet popularized, I am wondering when the industry will widely developing 64bits software, and when the 64 bits Windows been popularized?
64 bits OS environment offer better security as compared to traditional 32 OS environment, but the problems are:
1. For gamers, still stay on the current Windows XP SP2 for widely game compatibilities.
2. For old office, still stay on Windows XP SP2, for support for the old accessories (scanners, printer, and other add-on peripherals)
For new system installer, i would recommend the Windows VISTA, because of the technology is keep on staying ahead.
The road to 64 bits is tough, Microsoft is implementing the close source Windows OS development, which is contraly to LINUX open source software development, hence restricting the development of the software under 64bits environment.
