I'm looking for a Tablet for a special needs child, it has to be android o/s. The only feature i care about would be the ability to remove the battery and separately charge it on a charging station as the child is very hard on usb charger connectors. I've been searching for about 2 days with no luck, plenty of cellphones that fit the bill, no tablets. (not concerned about brand/price/bells and whistles ect, just peace and sanity this will bring to my home) I appreciate any help.
