On the Android side of life things get more divided since any manufacturer can put the Android Operating system on their devices. Just like with Apple there are numerous versions of Android ie; 1, 2, 3, 4, 5 and recently 6 and of course their associated names ie; Ice Cream Sandwich, Jelly Bean, KitKat, Lollipop, Marshmallow and so on.
Linux is new to the tablet scene. However, since they are a full blown computer operating system they could be a most viable option. CompuMatter is expert at all things Linux so if you have a Linux tablet, you can certainly bring it here.
