Zitat:
As with Windows XP Professional x64 Edition, the various Windows Vista x64 versions represent a serious compromise and are, thus, not necessarily a clear choice for many Windows users. On the positive side, the x64 versions of Windows Vista are far more secure and reliable than the 32-bit versions. The also support enormous amounts of system memory, which can be important in markets such as digital content creation, engineering, and even gaming. On the other hand, the x64 versions are also far less compatible than their predecessors, with both hardware devices and software, and these incompatibilities will ultimately make the x64 Vista versions less attractive to most users. Within the next few years, the majority of Windows users will almost certainly move to x64-based PCs. But I'm guessing that the 32-bit versions of Vista will dominate throughout this product's lifetime because of compatibility issues. Think of Vista as the "line in the sand" for the x64 platform on the client: Post-Vista, it's likely that most compatibility issues will be resolved or rendered moot by new hardware and software versions that are more x64-savvy. By that time, migrating to x64 will be a no-brainer, and hopefully Microsoft will support upgrading 32-bit Vista versions to future 64-bit Windows versions.
