I can't wait until Smartglass becomes better. I have tried it on a few things.
Bought Dark Knight Rises and found out that Smartglass will only fully work if you completely download the movie before watching it. If you stream the movie from the market place, Smartglass assumes you are renting the movie and locks most of the content. It says you need to buy the movie to look a certain things.
For Xbox Karaoke on the 360. It limits the ways you can search for songs by genre only. You can not search by artist or song name, though you can do this with the 360 remote. Plus if the screen on your tablet/phone time out Smartglass disconnects. Once you turn your phone/tablet back on you need to reconnect Smartglass, sometimes this takes several tries and sometime the device needs to be restarted.
I have been using a Windows Phone 8 Nokia Lumia 920, iPad (G1) and a new iPad (G3) to play with Smart Glass.
When it is working, Smartglass is awesome. It just has a way to come.
