i have a windows 7 phone, i can use smartglass to navigate the dashboard and use IE, BUT THATS IT,
i have forza Horizon it doesnt show the map, i have halo 4 and it doesnt show anything in that either, so far i think its a major let down, i even brought an android tablet to see if it would work on that....... LOW AND BEHOLD it didnt! i could do all the things i could only do on my phone, so i sold that!!
its fully functional if you have any device running windows 8 but thats it,
so all this spill about 'it works with any device you currently own' is bull!
WORST PART ABOUT SMARTGLASS is that you doent always manage to sign in
now ill wait to hear you all say it all works fine for you on all ur non windows 8 devices lol.
