The Seattle Post-Intelligencer quotes Microsoft as saying it did all it could to educate customers, retailers and partners about the distinctions between Vista-Capable and Vista Premium-Ready.
Like many Microsoft watchers, I have found Microsoft's categorization murky. My ZDNet blogging colleague Adrian Kingsley-Hughes says the same.
Can all Vista-Capable machines run Aero Glass? Can some run it? None? I still am not entirely sure. And Microsoft's Web site does little to make that clear.
Microsoft's "Make the Move to Vista" Web site explains "Vista Capable" in the following way:
"A new PC running Windows XP that carries the Windows Vista Capable PC logo can run Windows Vista. All editions of Windows Vista will deliver core experiences such as innovations in organizing and finding information, security, and reliability. All Windows Vista Capable PCs will run these core experiences at a minimum. Some features available in the premium editions of Windows Vista—like the new Windows Aero user experience—may require advanced or additional hardware."
