Pro Familiar Windows Interface
As opposed to unfamiliar and purpose-built Linux distros, Windows still reigns supreme for sheer usability and ease of use.
Pro Customizable UI
There are many that can be used to customize the MetroTile screen and add custom tiles. Then, by adding custom tiles you can configure them to open any application or web page that you need. For example: Netflix, HBOGo or Steam.
Con Resource Intensive
In contrast to many dedicated solutions which can run on nearly anything, running a full Windows install requires decent hardware. This is not a lightweight solution.
You will need to purchase a Windows license.
