i’ve got a linx8 (windows tablet, had 8.1 but now running 10) so i’ll tell you what is great, and what isn’t. (things to check for).
the most important thing is to ensure it can be powered and use USB devices at the same time. this isn’t so much a problem with 10″ tablets, but is most annoying thing i’ve encountered with mine (it doesn’t have OTG) so its worth pointing it out.
This will enable things like playing films off of USB stickers/caddy while powered without the battery running out, additionally other useful things like using a USB keyboard+mouse.
If I were shopping for one now I’d go for one with a bluetooth keyboard intergrated case out-of-the-box, and budget for a bluetooth mouse. then you’ve basically got a small low powered PC. (talking of which, I have no idea about games performance).
i do have an iPad however it has a very different usage and since it cant have its storage boosted with microsd cards or usb stickers or caddys its a dead weight in some cases.
