I rarely listen or watch anything on my computer so I don't know if I'll even get Plex (even though it's only .99)
The stock media player app in the Revue works ok. I can see all my pics, music and videos. Some of the videos I shot with our old Canon 5mp camera won't play even though they are AVI files. Also the hd video from our Canon video camera won't play either. Not a big deal though.
