Have you played with Plex at all, Rob? I'm not saying it isn't a good application [service?], but the experience can vary. I use it on Android (phone, tablet, and Google TV), and it works very well but it pales in comparison to what you get in the Plex app for desktops. The desktop app is gorgeous, using the show's promotional art in the background and even playing the theme music for whatever show you're browsing through at the moment. It looks great and it does all of this automatically.

But on Android (and, I suspect, on a device like the Roku) the experience is very different. The shows just become plain lists. I wouldn't call it unattractive, it's just not the great UI experience I wish it were.

Then again, you've probably seen this and I'm only telling you what you already know
