I think these numbers are a testament to how good Windows 7 is. There was definitely a compelling reason to upgrade to Windows 7 from Vista, but, with Windows 7 being so good, Windows 8 is a tough sell for some consumers. In my experience, Windows 7 has been more stable than Windows 8. For average users, there's no real reason to upgrade.
