You can add apps to the TV by clicking the Smarthub button on the remote. The TV, however, needs to be connected to a Wi-Fi network or LAN to start downloading stuff. There are many apps to choose from, but the best addon for this TV is Skype that uses the pop-up camera on top to its advantage. Plus, this is also full blown media player, which can even play Flac files. We also liked the fact that the TV shows a dialogue box as soon as you plug in a USB drive. You can use this TV to do almost everything you would with a tablet. Just look at this as a large, very large, tablet computer.
