For giggles I've been doing some performance testing on a Surface Pro running RemixOS vs a Pixel C tablet. Interesting results so far.
The SP3 is trouncing the Pixel C in most regards, though 3D acceleration is an Achilles heel. ROS is based on Lollipop, so you're missing some features, but still have full Android ecosystem dual-booting with full Windows.
Seems like this might be the ultimate configuration for Road Warriors, enthusiasts, and multi-platform media consumers.
