QuoteAfter five years in development and endless feedback from Allchin and thousands of other testers, Vista is ready for the masses. It will hit store shelves on Tuesday. One day later, Allchin, as promised, will retire after 16 years with the software maker. It's not yet clear how Allchin's latest product will affect his legacy. While early reviews of the operating system have been lukewarm, Allchin said he is confident that time will show Vista to be a significant improvement over previous versions of Windows.
