Are they going to come to life and start holding 3rd Parties hostage?

Also I'm getting mixed messages because I have yet to see Nintendo Announce Blu-Ray Playback support or DLNA Support.  That already loss them my living room.

Latency may very well be a problem, but there's something to be said for Microsoft's Smart Glass as well. The fact that it could potentially support devices which are technologically more advanced than the Wii U gamepad is one such advantage. If you were using an ipad for instance you could be using multi-touch along with 'pinch' and 'spin' movements in a way that the Gamepad is incapable of doing.

I would bet the house that (relatively) no gamers or developers even try to use SmartGlass.  Usually people toss around the word "gimmick" to dismiss a concept, but I don't even think SmartGlass qualifies as a gimmick.  It's more like ... a thing that exists .....

My guess is that SmartGlass functions are going to be vary basic.  How can you do anything complex across such a varied set of hardware?  Is the person on a phone or Ipod? Android, Ipad?  What version? Screen size and functions are so varied that it would be hard to get too complex as a developer.
I will believe it when I see it- Microsoft programming for ios devices and doing it well on top of that is hard to fathom.

I don't think the SmartGlass strategy works nearly as well. With the GamePad, the screen in on the controller. You can use the screen and the controller at the same time. That's why it works so well. With SmartGlass, you have to keep track of 2 separate things. It doesn't seem as intuitive.
