How come? I'm thinking of doing the opposite.
Xbox Music sucks on android. There's no way to find new music beyond manually searching for specific songs/artists, meaning the only way I can discover music is through the desktop. While I prefer Outlook and Xbox Video (much more selection on XV than Google Play, they have deals on bundles of movies, more anime, etc), I'd much prefer to have it all on one account if I can.
The main reason for the move is that I moved from Windows Phone/Blackberry to Android (Moto G Second Gen had a good Black Friday deal), and now my Surface RT is crapping out on me. The only Windows Tablet that really appeals to me is the Lenovo Miix 2 (due to some insane deals on the 64gb model) has touch screen issues. The only other options I'd probably consider (Lenovo Yoga 2 Tablet w/ Windows or Surface Pro 3) are way overpriced of unavailable in my country. I'm thinking of just going all in on Google's ecosystem due to better hardware availability and going with the new Lenovo Yoga 2 tablet (I have a Lenovo Yoga 2 Laptop and love it). MS's ecosystem is nice on their products (and from what I've heard, iOS) but are bad or outright missing on Android.
TLDR: MS's services suck (Xbox Music) or aren't available (Xbox Video) on android. Since my new phone is an Android phone and I need to move from my dying Windows tablet, now seems like the best time.
Why not get a Netflix subscription and a DNS/VPN blocker to go with it? The Netflix regions around the world have a lots of great movies/shows to fill in the gaps of the America library.
I live in Canada (which has a TON of TV but basically no modern movies beyond 5-6 they shuffle out every few months) which I personally love, but I have a pretty decently sized collection on Xbox Video. My main concern is having two libraries of movies (start buying them on Google Play), or if I should just stick with MS on Xbox Video?
