I imagine the 3GB number is there because they figure it's easy to reserve it now and give back later, where the reverse you're basically screwed. I also have no idea what people will and will not want to do with their tv. For a lot of people it's probably the biggest and best screen in their home. Will they want to do some basic photo touchups or make a powerpoint presentation on their tv? Maybe. If I had all the answers I'd probably be a millionaire. Adding support for bluetooth mice for apps would probably be a good idea. I know bluetooth keyboards already work.
Naw, I want a EA "In Your Face" app so I can use Kinect to record my well prepared and well thought out custom animations for when I score in Madden, NHL and other sport titles.
Or an Elder Scrolls avatar app thats forward compatible, so I don't have to spend an hour figuring who I want to be when I could be exploring Tamriel.
How about a CGI like Youtube app that makes use of the console camera for motion capture. Make your own little story/clips using 3D characters.
And I want to migrate through a bunch of heavily used apps like I use browser tabs versus spending time waiting for them to individually load.
How about map apps? Instead pressing pause and given a simple 2D representation that just a tad bit more informative than the hud map. How about a work around where the app provides a full 3D model that would make Google envious? In futuristic games like Watch Dogs or Destiny this makes perfect sense. You could also use it to learn multiplayer maps without having to do so in the midst of a match. In SP you could plan your routes more carefully and strategically. Since it running in the background there is no need to load making for a more seamless experience. All without devs providing resources reserved for the Game OS.
I don't need mobile or PC apps on my console thats what my PC and mobile device is for, what we need is apps that are relevant to the living room, TV and games.
If you want vibrant console app ecosystem with multitudes of apps providing for a whole host of functionality that used by the vast majority of the userbase, it can't take a backseat to the primary function of the console. You can't treat apps like a red headed step child and think the ecosystem will grow. The smartphone and PC apps are given 1st class citizenship on the platforms they service. It should be no different for consoles.
