This unit comes with a multitude of different functions. We start off with TV, which can be used with cable or satelite connections. Then it's a DVD player which also has an A/V out which means you could hook it up to your big TV as well. Then it has two slots for external media: a USB slot and an SD card slot. With these you can download movies and music off of the internet and play them right on this little black cutie. As if this weren't enough, you also have the capability of playing games on this, and it comes with a game pad so you can really get into the fun. Now it gets really good. This TV can use 3D Media, so you can watch all of your favorite 3D movies on here! This really is one of the most compact, functionally incredible and your all-in-one go-to piece of media technology! And it's super light weight too! But, just to put the cherry on top, it also has a radio, so you can listen to all of your favorite over the air tunes as well!
