I recommended the PocketBook Era to someone who has an Oasis in a sister comment. It supports Bluetooth remotes, keyboards, probably any Bluetooth HID with buttons. You just map any button press you want to reader actions (including ones beyond just page turn). It doesn't support input from them outside the reader interface, but fully usable without the touchscreen (you can map turning it on and off to the button combos too) when reading with a remote or the built in physical buttons.
