I'm sort of neutral on the Start Screen I can definitely say it can be improved with Blue/8.1 ,9,10 etc.....however I use it when I need to like any tool and it does not really bother me,I hope Microsoft keep coming up with new ideas etc and try to improve on them etc rather then doing u turns.
I can understand some people not liking a certain OS or two for example Win8,just like I don't like some of the Linux Distro's but like others ,however I still think Linux is great and it does not mean the ones I don't like are bad or are no good.
Some of the changes in Win8 a few users find hard to adjust too, we all know what they are but like any OS nothing stays the same forever.
I just hope Microsoft move forward rather then backwards and keep new ideas coming.
