There needs to be a Windows 10 app for laptop/desktop/phone/Xbox, etc. Microsoft has made this super simple for developers. You drop in your Android app, and it spits out a Windows Universal App which will run on any Windows 10 device, be it a Surface tablet, laptop, desktop, phone or Xbox.
It was a real bummer when Verizon killed the Fios Xbox 360 app. That was what I used on the 2 times a year I watch TV on a basement television. I refuse to pay another $12/month to put an STB for a tv that gets used so infrequently.
