I would also suggest the Cube Mix plus – although it “only” has 4GB, this is enough for nearly everything. And in those few cases, where 4GB RAM are not enough,I think the CPU (despite very fast for such a device) wouldn`t cut it anyway. Windows 10 is less ressource-hungry than it´s predecessors.
The Display on the Mix Plus is good enough, overall the device is VERY fast. The only Thing that`s annoying with the Cube is that it does get hot.
Minor other things – for me – are the 3:2 form factor and the battery could be better. But those two points go for all Windows Tablets I know, including the very pricey Surface4 Pro.
An iPad Pro with MacOS X and maybe even triplebooting with Android and Windows would definitely be nice…
