Either Apple isn't operating on the Gregorian calender, or these updates are just straight-up late. Either way, we're pretty stoked to see the suits in Cupertino finally wise up and allow Microsoft's best OS ever to work on its machines, as it has today issued new Boot Camp software (v3.1) for both 32-bit and 64-bit users of Windows 7. The updates add native support for Win7 Home Premium, Professional and Ultimate, and in case that wasn't enough, they also fix "issues" with the Apple trackpad and add support for Apple's wireless keyboard and Magic Mouse. You'll also find model-specific drivers floating around to add even more support, and the Boot Camp Utility for Windows 7 Upgrade is said to "safely unmount the read-only Macintosh volume on Windows Vista" when upgrading from Vista to Windows 7. Hit those links below for all the bits and bytes that you've been so desperately waiting for.
Update: we're hearing reports that the 27-inch iMac is responding to Windows 7 with the Black Screen of Death, so make sure you use this tool from Apple before installing Windows 7. Too late? Then you'll have to manually remove the offending default ATI drivers by starting from point 4 on this page (hold down Option key while booting up to select the Windows install disc, by the way), and then try the Boot Camp update again.
