Windows 7 seems to have performed well so far. I personally heard many positive things about it. Businesses are moving toward it, too (Windows 7 Scores Enterprise Wins). However, from my personal experience, I do not have a strong feeling for Windows 7 over Windows Vista. I have been using Vista for the past two years and found many improvement over XP. For example, the snipping tool, easier wireless and network configuration, broader hardware support, etc. I bought a new HP tablet about 3 months ago with Windows 7 installed. But so far, I don't have plans to upgrade my other two Vista computers. I may have missed something about Windows 7. So, what's your idea? What's your experience with Windows 7 where it absolutely wins over Vista? Can you share it?
Don't forget that, as a CIS 2010 student, you can get a free copy of Windows 7 from MSDNAA: http://msdn.e-academy.com/elms/Storefront/Storefront.aspx?campus=gsu_cis
