Windows 8 was out few day a go.new look new apps better navigation ways i hope this will help you understand it more in my Windows 8 consumer guide.
i will start with the first screen you stumble with using Windows 8 .
you can see here that it has been changed completely from what we know . what's good about this new screen that it has all the information that you may need in one place and you can see theme in one time, such as your contacts and weather and many many staff you may need
you have the power to organize theme as you like .navigation on it is faster then ever .
you will notice the beautiful design of it with the Heavy colors and simple look of the words on your screen .and i can't describe how fantastic the applications animate.
