Back in 2006/2007, Windows Vista momentum ground to a halt partially because Microsoft's partner ecosystem wasn't ready with the necessary hardware drivers. For Windows 7, however, this hasn't been an issue at all. In fact, the only major vendor not to support Windows 7 with their current products is ... Apple.
Previously, Apple promised to provide Windows 7 drivers through its Boot Camp utility, which lets Mac OS X users dual boot between that OS and Windows, by the end of 2009. So they're late. But these drivers can and should have been delivered to customers when Windows 7 shipped, in October. I guess the company was too busy fixing a widely-reported user data deletion issue in Snow Leopard to bother supporting a competing system that just works.
So thanks for nothing Apple. We know you're scared of Windows 7, but come on.
