Air Video TV app. This alone is worth the entire price of the Apple TV. No more air playing with an iOS device, now you can browse your computers files directly without having to convert anything. It decodes on the fly video files like mkv, avi, mov, MP4 etc... It's exactly what is the best thing about he Apple TV 4. I'm now going to replace all 5 ATVs in my home thanks to his app. Also, streaming is blazing fast now withe the new processor. Buffering time is also non existent. Fun fact: Air Video also can peek into rar or other zipped files and play from inside the compressed file!
