To be completely frank, when it comes to Windows, I'm a fan of less is more, but if you happen to disagree and want to give an automotive flavor to your desktop / laptop, Infiniti, Porsche and Ferrari have all teamed up with Microsoft to provide Window 7 users with special backgrounds, slide shows, screen savers and color customization as part of the new Windows 7 Desktop Theme Gallery.
Notably, this is the first time that Microsoft has made the packages available to partner companies. Aside from the three car brands, there's also a theme for Ducatti as well as other companies/ brands/ games such as Bing and Gears of War.
Windows 7 users can download from the theme pack from Microsoft's dedicated page by clicking here.
