I watch a lot of television from foreign providers. Some are only available if using a virtual private network (VPN) to hide your actual location (i.e. Al Jazeera, which no longer provides Internet viewing in the U.S.). If I understand the Stick correctly, I should be able to install my VPN on the stick and then view programming from the source's web site as I would do with a regular PC with Win 8.1, except that this "PC" is connected to my TV's HDMI port and always accessible. Basically, making my "smartTV" truly "SMART"!
It's basically a standard Windows PC. If you can do whatever with a desktop PC, it should similarly be possible with this device, though with power and performance limitations.
