The site, in beta form, lists about 9,000 hardware and software products and their Vista readiness. Microsoft had planned on launching it on Tuesday, but encountered some unspecified issues.
With that resolved, folks can now feel free to pick on Apple for a while, given that it has had glitches with both its MobileMe service, much of which is still not operational, as well as activating new iPhones.

The company has also launched a separate effort specifically for small and mid-size businesses, offering free technical support for Vista.
