When I bought this Samsung Series 9 laptop, first thing I did was remove Windows 8 (for obvious reasons). Since then, I've been running lubuntu, but thought I've give Windows 10 a shot. It wouldn't play as a VM, so have installed it natively (restored previous Windows 8, then took the offered in-place upgrade; it just picked up the BIOS embedded key and ran with it).
First impressions - it's in a different league to Windows 8/8.1 in terms of usability.
I suspect the runtime on the laptop on batteries will be much less - the machine runs warm whereas it never ever broke a sweat with lubuntu, and I don't have to work it too hard for the fan to come on.
S'nice though. What Windows 8 should have been.
