From watching a few videos, the cube i9 is one of the top rated tablets Chris has used. Its not dual boot out of the box, but you can make it dual boot with remix os
Teclast Tbook 16 Power are to my knowledge the tablet with the most impressive spec (Atom 8750 chip and 8 gb RAM), but it suffers from majour Thermal issues if I remember Chris review correctly.
More or less any tablet can be made to dual boot with remixOS, some work better than others though
This is a nice applock to protect our data like photos ,video, archives, texts, etc., specially anti-thief is best one and its capture and good app install it and be happy for personals, make your smartphone safe!
