The Cool Factor
Damn you guys really have a complaint to make about everything and you crack me up how you say that the user base is limited, there are millions and millions more pc users (windows) than any other platform and probably ALL other platforms combined. There are also millions of xbox users. The consoles ps3 and xbox 360 currently and whatever new versions that launch over the next few years are becoming more and more of a focal point in the living room. I don't know about all you guys and girls but I have a ps3, a cable box and a hi definition tv in my living room nothing else no dvd player/bd player. When I want to watch movies I either stream it from my pc or I stream it from the net via my console and this type of useage is only going to increase over the short to mid term.
Here's what's really cool with smart glass, I can decide what I want to watch on my tablet or phone instead of needing to use my ps3/xbox controller to navigate through more clumsily then I can switch the movie/show from the phone/tablet to my tv for everyone to enjoy. It makes my "jukebox" a lot more fun to use and then I can get automatic information sent to my phone or tablet while I am watching it too. The Reg comment you can just search imdb for information from your android or ios device = fail, wouldn't you rather have information automtically provided than having to focus on searching for it yourself........enough said.
Don't get your panties in a bunch apple/droid users you will get access to this cool tech eventually or you could actually consider that perhaps someone else (msft) has something cool that you obviously want or you would not be complaining that it's not available for your device in the first place right.
