Windows Phone 7 was built with the user put first, combining simplicity with a more seamless mobile experience. Instead of navigating through lists of applications and functions, you can scroll up and down my fully customisable home screen.
From here you can choose to use any of the five supplied hubs, simply by pressing the one you want. These include the office hub, the music and video hub, the people hub and the me hub.
By pressing the relevant tile, you can then more easily navigate to what you want, without the need for scrolling through pages of applications.
