Android phones, apps and tablets

You can get a Now TV box for a tenner and sideload Plex on it. Remote viewing is decent when I've used it so back-end can be at your place if you have an always on PC/NAS and decent internet connections.

Just checked this out, seems pretty decent especially for a tenner.

I've got Plex set up at home already, but I've been pretty disappointed with it's remote performance so far, but then that's been due to mobile network issues rather than Plex issues.
