I just bought two new laptops that both sport fancy "Windows Vista Capable" stickers. Hewlett-Packard--yes, I bought from HP despite the spy scandal that involved CNET, mea culpa--even throws in a free upgrade to Vista.
But when I was discarding the cardboard boxes in which the Pavilion PCs shipped (from China), I noticed warning stickers:
"Not all Windows Vista features are available for use on all Windows Vista Capable PCs. All Windows Vista Capable PCs will run the core experiences of Windows Vista, such as innovations in organizing and finding information, security, and reliability. Some features available in premium editions of Windows Vista--like the new Windows Aero user interface--require advanced or additional hardware. Check www.windowsvista.com/getready for details."
A quick check on the HP Web site tells me that the systems I bought should be able to run the premium editions of Vista, thanks to the optional upgrade I selected to 1 GB of RAM. Phew.
The laptops are actually going to be used by my brother, so I'll leave it up to him if he wants to upgrade to Vista. Since the PCs will be used mostly for business, I imagine that he might want to stick with the familiar Windows XP Professional for now.
