Some people are afraid to adopt the change while others eagerly wait for new things, I'm currently in love with Windows 10, had waited for months to get the stable release, in a few months many more users will fall in love with it even if they don't take initiative & install it on their machines but they'll see around, read around & will get motivated to try this operating system, no doubt windows 8/8.1 were very buggy & incompatible to many software (I remember had to use windows 7 to use adobe after effects) but afterwards it started giving us better experience then the famous one windows 7. Windows 10 will rock.
