Two days ago, I bought a Slatebook X2 to replace my aging Rockchip rk3066 based tablet for playing RR3.
The Slatebook runs RR3 with ease, but I do have issues with the touch screen. I'm playing type B controls and occasionally the on-screen braking doesn't register, or only briefly. Causing crashes or big off-track excursions.
I'm thinking about returning the slatebook. If others are having the same problems, I'd go for a refund and buy something better/faster later this year. If I got a semi-defective Slatebook exchanging it for another one might be a better option, as I like the performance and features of the tablet very much.
