How many of Apple's Windows-compatible applications are ready for Microsoft's latest operating system, Vista? According to the Mac maker's own tech support site... er... none of them are.

Earlier this week it emerged that iTunes isn't yet ready to run on Vista, and neither is the iPod it seems. Apple's current advice is for iPod owners to wait until the next release of iTunes before upgrading from Windows XP to Vista.

But iTunes isn't Apple's only Windows app - it also provides versions of Software Update, QuickTime, Bonjour, AirPort, iDisk Utility and AppleWorks for Microsoft's operating system. According to Apple's own Windows compatibility checklist page, last updated on 2 February, none of these programs should be run on Vista.

There's no indication when any of these tools will gain formal Vista compatibility - Apple just advises users to keep an eye on the compatibility page.
