The Nexus Q's feature-set is deliriously limited. Here's what you can do: play music uploaded to or purchased from Google Play, play videos purchased or rented from Google Play, and play YouTube videos, from an Android phone. That's it. No Netflix, Hulu, Rdio, Spotify, or Pandora. No playing videos from your phone or anywhere else on your network. No playing music downloaded from elsewhere. No viewing photos. No web browsing (as painful a process as that is on other media streamers). No apps of any sort (a podcast app, for example, would be welcome). It only works with newish Android devices (at launch, it'll support devices running Ice Cream Sandwich and Jelly Bean, like the new Nexus 7 tablet). My recurring thought while testing it: "Oh, you can't do that either, huh?"
