I've always been curious about these and other windows tablets.
I was bored of my iPad & went for a shield tablet.
The shield tablet is powerful but buggy. I think I've spent more timing trying to fix gamestrean than use it.
However it does let me remote play my PC and ps4 but not Xbox.
I'm pretty excited to try my Xbox one on the linx, all going well I also plan to run.
Steam stream or PC version of moonlight.
Ps4 remote play ( when a modder finishes it at XDA )
Not sure what else yet
