My desktop and laptop have Windows 7 installed on them and my wife's laptop has Windows 8 on it. As someone who spends 8-10 hours a day on their computer programming/debugging/everything users on this site do, I'm not sure I could handle working in Windows 8 all that time. I feel like Windows 7 got so much right for power users of Windows, and that Windows 8 is for casual users of their computer.
