I'm very curious to try a dual-boot Android + Windows tablet. There seem to be a lot of (I assume Chinese) brands I've never heard of selling these and they're really cheap. e.g.: http://www.gearbest.com/tablet-pcs/pp_141283.html Does anyone have experience with these types of devices? Any comments? Some things I'm particularly interested to know: - Is one brand any better than the others? - How is the SD Card handled - is it somehow shared between both OSs or does it get dedicated to one OS? - Would an OS update (e.g. Windows 8.1 to Windows 10) break dual-boot functionality?
