So then it runs everything through a browser on your computer, and you have to navigate the file system? Seems like you aren't understanding the appeal/use case of plex. I can use a nice clean interface on my TiVo, Phone, Computer, Roku, AppleTV, X-Box... And watch TV, unless I'm trying to watch something on the computer I don't have to get out a clunky computer to play anything.

Videostream has a basic media library as well, and you can choose stuff to play from your (Android) phone/tablet. Works quite well. I've used both Plex and Videostream and find myself using Videostream most of the time.
