Thanks for a tip, I learned the Cube Thinker i35 has the same screen digitizer and pen as the Surface Book, so it’s not just the 13.5″ 3000 x 2000 Surface Book IPS but even the N-Trig stylus tech used. Below I ran a very quick test of the Surface Pen I got in just to confirm this. And it seems to work exactly how I remember on my old Surface Pro 4 I own for about 6 months.
But it’s not all positive, the Thinker i35 so far as one flaw. Thermals, it reached 82 degrees C taxing the CPU, which isn’t an issue. But if you Game or intend to push but the Intel HD 615 graphics and 7Y30 CPU temperatures will hit 92 degrees, however not triggering thermal throttling which is at something. I did my usual mod, new thermal paste, 15mm x 15mm x 1mm copper shim and then on top, a thermal pad to transfer heat to the rear plate. As a result, it dropped max temps by 25 degrees C. A huge improvement! The Thinker i35 is still on sale for $616.
