The New York TimesTechnology section has an article online today "On the Horizon: A Vista Upgrade." In it, the author provides some answers to the question: How can I find out if my current computer hardware (including my scanner and printer) will be compatible with the coming Windows Vista system? Will this be as simple as merely downloading new drivers?

From the article...

"If you are holding off on any hardware purchases until after your Vista upgrade, Microsoft recently announced that about 250 hardware and software products for sale this holiday season will be labeled “Works with Windows Vista” or “Certified for Windows Vista.” Products with the “Works” label will work fine with Vista, but “certified” products (including some graphics cards), will be able to take better advantage of certain Vista features.

If you are planning on installing Windows Vista on your current computer, you can check to see if your hardware can handle Vista’s system requirements at www.windowsvista.com/getready."  

Many PC OEMs (like Dell, HP, IBM, Gateway, Toshiba, Sony...), third party manufacturers and software makers are beginning to list the products that are compatible with Windows Vista. To check your current PC, you can evaluate your current PC with the Windows Vista Upgrade Advisor.
