I had a 2 XS for a while, only used it for Netflix and Plex. The Netflix app is pretty good.
Did not like the Plex app at all, the interface is horrible, looks about 10 years old, coming from XBMC and skins I lasted about 3 weeks before I couldn’t stand navigating/looking at it. Its also slow and not intuitive. Which is a shame because it uses so little power. I also had issues with Plex Media server in that it kept hanging and keeping my server awake when it should’ve been asleep.
The £49.99 deal from eBuyer for the 2XS is a bargain at the moment.
