Don't even bother with those Chinese tablets. They are passable for media consumption, but absymal for anything else. Buy something like a refurbished Dell Latitude series instead. Keyword here is you said "long trip'. When you buy something that made a lot of tradeoffs to achieve that price point, you are going to be frustrated.
I'm considering one for media consumption (Netflix, high-bitrate 1080p video) - do any have good battery life?
* I bought it thinking that this would be a cheap Win10 based Netflix / Comic Reader. Windows 10 is not really a touch friendly OS. You will end up booting into Android and installing apps. Even then, there are frequent crashes / Some apps won't work because the Tablet does not meet DRM requirements.
* Netflix on Android only runs in HD with certified devices. Else you're going to be getting streams in 480p max.
* I apologise for the Caps. I got burnt by 2 of these tablets. (My fault, because I was expecting an iPad like experience without paying the price). I'm hoping that I can give you what to expect if you decide to buy one.
