OK so here is the problem, my wife and I each have a windows phone 8 nokia lumia 920. We also have an xbox 360, the xbox and 2 windows phones all have different microsoft ids/xbox live logins) if i could just log in with a different account on smartglass i could then use it with my xbox. but i can't so apparently all three have to be the same microsoft id, which means all the contacts would be the same on each and that i would have to rebuy and redownload every app/xbox live game i have purchased on the 3 different systems. so i would lose lots of money and valuable time, this seems like a huge oversight, i bought into the windows phone ecosystem, but if microsoft plans on having families with 5 windows phones, they should really make it easier to connect to one xbox.
