What will users decide on? I would bet windows 7 as there will be way too much work to do to incorporate 8.1 so soon in the corporate environment. I see a butt load of windows 7 sales still coming. I also see more okay-ness or less hatred with 8 with upgrade 8.1. Still though Balmer-why can't I install my QB 2012 on Windows 8 or 8.1?! Did you forget backward compatibility? I shouldn't have to create a windows 7 virtual environment to do this.
