Use LLN without a laptop / pc

I usually Netflix lying in bed using Apple TV. Using my laptop so I could use LLN is a bit of a distraction and I’d rather avoid it. I’m not really sure if there’s an answer, but I’m looking for a solution that enables me to use LLN in these circumstances, preferably using a remote to interact with LLN (probably just for single-word translations).

I don’t know if a Raspberry Pi would be an answer, or some other form of micro PC with a remote or keypad. I have been looking at some Bluetooth mouse / keypads, but there’s too much choice just to take a random pot shot.

Has anyone got any ideas?
