One of my favorite features on Windows 10 Technical Preview is task view. By swiping from the left side of the screen, I can see all the open apps and quickly switch as needed. Windows 10 goes a step further with virtual desktops. This lets you group apps in multiple desktops. For example, you can place Outlook, Twitter, and the web browser in one desktop, while you have Netflix in another desktop. The organization is up to you.
