In all these years of Evolution, Linux now delivers a pleasant experience to even an average non-techy person. People who have tried / used Linux for once always make their way back to it even after using Microsoft Operating Systems. Dual booting a Windows PC with any Linux Distribution is a common practice for almost all Linux users for the purpose of enjoying the power of Linux and using Windows for software / games that are particular to Windows. Some have managed to switch completely to Linux, some just dual boot it.
