Good news for those planning to run Windows Vista. Nero has announced that the version of Nero 7 currently available on their website is is ready for Windows Vista Release to Manufacturing (RTM).
Nero, leaders in digital media technology, announces today that its premier digital media software suite, Nero 7, is ready for Windows Vista Release to Manufacturing (RTM).

Having rapidly addressed the latest developmental changes to Microsoft's highly-anticipated new operating system through the RC1 and RC2 phases, Nero now offers its Windows Vista-ready software to consumers online at www.nero.com. Current Nero 7 customers will also be able to download this version free of charge at the company's website.
I'm guessing that we're going to see a new version of Nero in the next day or two as the current build, version 7.5.7.0, has some known issues with Vista. If you'd like to read more, Nero's entire press release can be found here.
