This is really great. Stunning video, great sound, access to tons of ...everything. The limits to this device are defined by the limits of your imagination. Just imagine the ability to watch video, pictures, news, email....anywhere. Need a internet connection...just tether it to your cell phone.
Output:
Positive Review
