"WinXP is the Model T of operating systems"

"In my experience, coming to Windows after using Linux and KDE for years, WinXP has fewer features and is less customizable than KDE. I am not just talking about “eye candy” either. I am less productive when using WinXP. Instead of working in the way I prefer, I am forced to modify my work habits to match WinXP's limited feature set. WinXP is the Model T of operating systems — any color as long as it is black."
