I think the picture provided here, pretty much says it all. LG has assembled a Smart screen listing a wide range of content, as well as the ability to select inputs, settings and internet access. LG even lists an LG Cloud service.
All considered, there's a ton of both subscription based and free content available. Some of the subscription content includes MLB.com, Netfix, VUDU, vTuner (internet radio, Amazon instant video, Spotify, and the list just keeps going.
There's even a 3D channel, or you can search the web. And thanks to the microphone option on the Smart remote, you can talk through some of this. It was easy to select Search, with the Smart remote, and speak "projector reviews". LG's search uses Bing (I don't know if that can be reconfigured), but I"m pleased to report that our website came up first for that search.
In other words, LG is providing similar types of access to content of Roku, or my PS3. Unfortunately I don't have the time to look through all the entries, but there's lots of pay TV, movies, and more.
